Best Cummins 6.7 Scan Tools for RV Diesel & DPF Regen

The internet seems to give me six different answers about which scan tool actually works with my 2019 Fleetwood's Cummins 6.7L—am I missing something obvious here? Need comprehensive coverage for reading and clearing fault codes, monitoring engine parameters, and performing forced DPF regeneration cycles.

Considering several options including the Foxwell HD500, Ancel heavy-duty scanners, and various BlueFire/Inline adapters available through different suppliers. Price ranges vary significantly from budget OBD2 adapters to professional-grade diagnostic equipment.

Looking for detailed comparison of available scan tools specifically for Cummins 6.7 applications - both professional-grade and DIY-friendly options. What are the key features, compatibility considerations, and real-world performance differences between the various diagnostic solutions for this engine platform? …more

RV Underbody Lighting Installation: Complete DIY Guide

I'm wondering if anyone else walked out this morning and spotted how embarrassingly bland their RV's underside looks compared to those slick LED setups online? My husband and I are pretty new to the RV world and I've been wanting to add some nice ambient lighting underneath our Class A motorhome. I think it would look really cool when we're set up at campsites in the evenings. I've seen other RVers with these gorgeous blue or white lights that make their rigs look so professional. We're definitely beginners when it comes to electrical work, so I'm hoping someone can walk me through what's involved. Is this something we can tackle ourselves or should we find a professional? Any product recommendations would be super helpful too. Thanks so much for your patience with us newbies! …more

LiFePO4 Battery Not Charging in RV: Complete Diagnosis Guide

Planning my next boondocking trip when this faint electrical burning smell started coming from my battery compartment, and my 950W flat mounted plus 1200W ground solar setup isn't charging my LiFePO4 batteries at all. My LiFePO4 batteries used to charge up beautifully, hitting 100% by late afternoon like clockwork.

Now? Total drama queens. This morning we woke up at 18% charge, and after a full day of glorious sunshine, we're sitting pretty at a whopping 63%. With 2150W of solar, I should be swimming in electrons! But instead my batteries are acting like teenagers - moody and refusing to cooperate.

I'm starting to suspect something's gone wrong, but honestly, I have no clue how to properly check LiFePO4 batteries. Are they actually broken, or am I just doing something monumentally stupid? What voltage readings should I be looking for, and what else should I check before I start panic-buying new batteries? …more

2003 Ford F53 Wheel Bearing Grease: Best Products

I'm wondering if my grease choice is wrong for my 2003 Ford F53's front bearing replacement when my neighbor's identical motorhome runs perfectly after his service. The original grease that came out was a dark gray/black color and while there wasn't any catastrophic damage, the races showed enough wear marks that I decided to replace everything while I'm in there.

I've been researching different options and keep seeing conflicting recommendations. Some people swear by standard lithium grease, others recommend full synthetic formulations, and I've even seen mentions of specific brands like Valvoline MaxLife and Timken. I know the F53 chassis carries significantly more weight than a typical pickup truck, so I want to make sure I'm using something that can handle the load.

I have the torque procedure down (30 ft-lbs initial, back off, then final setting at 17 in-lbs), but I want to make sure I'm pairing that proper installation with the right grease. What specific grease products work best for the F53 front wheel bearings, and are there any compatibility issues I should be aware of when selecting a replacement grease? …more

DC-DC Charger for Lithium RV Battery: Protect Your Alternator

Despite everyone saying I need a DC-DC charger for my lithium RV batteries, I'm skeptical about dropping $400 — will it actually protect my alternator? Just got a shiny new 2026 F250 (after my poor F150 basically begged for mercy when I hooked up my 2600RB) and had a 230ah lithium battery installed in the trailer. Now I'm reading horror stories about truck alternators and lithium batteries having some kind of electrical death match that could fry my alternator or damage the battery.

I keep seeing mentions of DC-DC chargers but honestly have no idea if I actually need one or if this is just RV paranoia at its finest. The trailer has solar and I've only got a 12V fridge drawing power when towing, so it's not like I'm running a mobile data center back there. Can I just use my truck's existing charge line to the trailer, or am I about to become another cautionary tale about expensive electrical mistakes? …more

HWH Levelers Flashing Blue Light: Complete Battery Reset & Troubleshooting Guide

Opened three different browser tabs trying to figure out why my HWH levelers are flashing blue — neighbor says dead batteries, dealer claims sensor issue, YouTube insists wiring problem. The blue light keeps flashing and the jacks won't respond at all - they won't go up or down. The only thing that seems to work is disconnecting the house battery for about 15 minutes until all the panel lights go dark, then reconnecting it.

I'm worried this might be a sign of something serious going wrong with the electrical system or the levelers themselves. Could this indicate low voltage issues or bad connections that might be unsafe? I really don't want to damage anything expensive or put my family at risk. What should I be checking, and is this something I need to call HWH about immediately? …more

Best OBD2 Scanner for a Ford E450 V10 Motorhome

Best OBD2 Scanner for a Ford E450 V10 Motorhome

Three different OBD2 scanners are showing 6 active codes on my 2015 Ford E450 V10 motorhome but every manual says this engine should only throw 2-3 max. I've been dealing with intermittent check engine lights and some transmission quirks, but my basic code reader just gives me generic codes that don't tell me much.

I keep hearing about tools like BlueDriver and some Ford-specific software, but I'm not sure what actually works well with these motorhome chassis. I need something that can give me real Ford-specific diagnostics, not just the basic OBD2 stuff. Has anyone found a scanner or diagnostic tool that actually works properly with the E450 V10 setup? I'm willing to learn something new if it means getting better diagnostic capability. …more

How to Replace Kwikee Super Slide II Drive Wheels - Step-by-Step DIY Repair Guide

Planning to tackle my Kwikee Super Slide II drive wheel replacement myself versus paying a shop $300+ after they started making that awful metal-on-metal chattering noise. I've found pieces of old rubber near the slides where it's completely broken off the wheel cores.

I've looked into replacement OEM parts which cost around $75 per wheel, and I would need 8 wheels replaced. I've discovered a DIY repair method using a PMC-790 urethane rubber kit that could potentially fix this for much less. The total repair materials cost me about $134, compared to $600 for new wheels.

My repair process involved creating custom molds using 2-inch PVC test caps, 2.5-inch and 5/8-inch hole saws, and mixing urethane rubber in a specific 2:1 ratio. I even added blue colorant for fun. Has anyone else tried a similar approach to restoring these drive wheels? …more

How to Sanitize Your RV Water Tank After Summer Storage - Complete Guide to Cleaning and Maintaining Fresh Water Systems

About to tackle sanitizing my Winnebago Navion's water tank this Saturday after months of Arizona summer storage — what supplies should I have ready? The fresh water tank was completely drained before storage and has remained empty for approximately 4 months.

Given the extended storage period and the harsh desert conditions with temperatures exceeding 100°F for most of the summer, I need to determine the proper protocol for bringing the water system back online. Is a simple rinse sufficient, or does this situation warrant a full sanitization procedure?

What is the recommended bleach ratio and contact time for sanitizing after this type of extended hot weather storage? I want to ensure the water system is safe for consumption before our next trip. …more

Hieha TPMS Review 2024: Complete RV Tire Pressure Monitor Test & Comparison Guide

Replaced my old TPMS last month but planning to install this Hieha system Saturday — should I worry about going budget for tire safety? I keep reading horror stories about tire blowouts and I don't want to risk my family's safety with unreliable equipment.

Has anyone actually used the Hieha brand long-term? I'm particularly concerned about accuracy issues and whether the sensors will actually alert me when there's a real problem. Are there better options I should be considering even if they cost more? I'd rather spend extra money upfront than deal with a roadside emergency later. …more

RV Tankless Water Heater Problems at High Altitude: Performance & Efficiency Guide

Already followed my RV tankless water heater manual's high altitude instructions, but I'm still getting terrible performance and efficiency issues at mountain campgrounds between 5,000 and 8,000 feet. My travel trailer came equipped with a tankless on-demand water heater from the factory, and I'm concerned about how it will perform at these higher altitudes.

I've heard that propane appliances can have issues with combustion efficiency when there's less oxygen available in the thin mountain air. Specifically, I'm wondering about quantifiable performance losses - like what percentage of heating capacity I might lose per thousand feet of elevation gain. I'm also concerned about potential operational problems like flame failure or the unit shutting down completely at certain altitudes.

For context, most of my regular camping is done below 2,000 feet where the water heater works fine, but these upcoming mountain trips will be well above 4,500 feet elevation. Should I be worried about the tankless system's reliability at these altitudes, or am I overthinking this? Would I be better off considering a replacement with a traditional tank-style water heater if I plan to do more high-altitude camping in the future? …more

EuroLoft Bed Lift Control Issues - Entegra Vision Troubleshooting

The EuroLoft bed lift in my 2025 Entegra Vision is completely acting up and driving me crazy. The bed won't budge when I hit up or down - just sits there like a stubborn teenager.

Weird part is the up/down LEDs that normally stay on while it's moving? They just do this quick millisecond blink and that's it. I already checked the obvious stuff - removed the mattress, no belt issues, nothing binding up. I used a 12V supply to test the motor directly, and it works fine both ways - moves up and down when I apply power with correct polarity.

I checked 12V power is getting to the red and black wires, and when I manually powered the Brown and Grey motor wires, the bed moved up and down. But oddly, when I removed power after testing downward movement, the bed kept dropping until the driver and passenger chairs stopped it.

Sounds like maybe the Power Controller or ACS (Advanced Control System) might have lost its marbles? Anyone dealt with this before? I'm wondering if there's a reset procedure or troubleshooting guide for this system. Really don't want to call a tech if it's something simple I'm missing. …more

Norcold 1210 Not Cooling with No Error Codes: Troubleshooting Guide

Looked at my Norcold 1210 refrigerator in my Grand Design 303RLS this morning — it's running perfectly normal but everything inside stays warm with zero error codes. Everything seems to work - the control panel responds, lights come on, and it even fires up on propane - but there's absolutely no cooling happening. Temperature reading shows 43°F and climbing.

What's making me nervous is that there are no error codes or alarms at all. I've checked the fuse and it's good, the little black box's red light is not on, and the fans aren't running. Usually when something breaks, you get some kind of warning, right? I'm worried I might be missing something obvious or that continuing to run it could cause more damage. Is this pointing to a specific type of failure, and am I safe to keep troubleshooting or should I stop using it immediately? …more

Complete RV Lithium Battery and Solar Setup Guide for Trolling Motors: Safe Installation Tips

Wondering if my 8-year-old lead acid trolling motor batteries that are barely holding a charge anymore are worth repairing or if I should upgrade to lithium? I need either a 24V or 36V lithium battery system, but I keep reading horror stories about people using the wrong chargers and damaging expensive lithium batteries.

I'm particularly worried about the charging setup - both for shore power charging at the marina and solar charging when I'm anchored out. I've heard you absolutely cannot use regular lead-acid chargers with lithium batteries, but I'm not sure what type of chargers I actually need. And for solar, someone mentioned something about MPPT controllers being required?

What specific type of chargers do I need for 24V and 36V lithium trolling motor batteries? I want to make sure I get the right equipment and don't fry a $1000+ battery pack. Are there particular lithium battery brands that are more reliable and safer than others? …more
Ford 7.3L Godzilla V8 Engine Lifter Failure: 70K Mile Analysis & Prevention Guide

Ford 7.3L Godzilla V8 Engine Lifter Failure: 70K Mile Analysis & Prevention Guide

Somewhere between shock and disbelief, I'm questioning my Ford dealer who insists my 2023 E350's 7.3L Godzilla V8 needs a complete rebuild after lifter failure at just 70,000 miles. The engine had one bad lifter and two scored piston walls, which seems pretty severe for a relatively new motor with what should be considered moderate mileage for a commercial-grade engine.

This has me concerned since I'm considering a similar setup for my Class C motorhome build. The 7.3L Godzilla has been marketed as Ford's heavy-duty solution, so seeing this kind of failure relatively early is troubling. Is this an isolated incident or are there patterns of lifter problems emerging with these engines? What should potential buyers be watching for, and are there any preventive measures or early warning signs that could help avoid this kind of expensive failure?

I'd appreciate any insights on whether this represents a broader reliability concern with the 7.3L platform or if it's just an unfortunate one-off situation that shouldn't influence purchasing decisions. …more
