RV Inverter Guide: Modified vs Pure Sine Wave - Safe Power

My multimeter's out and I'm ready to tackle this RV electrical mess myself — pretty sure the inverter's the culprit but need to know where to start. I have a 2000 Winnebago Ultimate Advantage with four deep cycle house batteries and recently installed a Xantrex 758 inverter to replace my old Freedom 15 unit. The first time I tried using the inverter power while unplugged from shore power, something very strange happened - a hair dryer in the bathroom started running by itself and wouldn't shut off when I tried the switch. I had to unplug it, and the handle was warm. The hair dryer appears to be ruined now.

When I bought the Xantrex 758, I paid around $725 for what I thought was a good unit, but I'm now learning there's a difference between modified sine wave and pure sine wave inverters. I wasn't aware of this distinction when I made the purchase, and it turns out the 758 is a modified sine wave unit. I've since heard that modern electronics, especially things like residential refrigerators, computers, and sensitive electronic components, can be damaged by modified sine wave power.

I'm really concerned about potentially damaging my new residential refrigerator, stereo system, and computer equipment. Should I be worried about using this modified sine wave inverter with modern RV electronics? Is the hair dryer incident a sign that I need to upgrade to a pure sine wave unit, or are there other factors that could have caused this problem? I'm trying to understand if my current setup is putting my expensive electronics at risk. …more

ECM Low Battery Warning RV: Complete Diagnosis & Fix Guide

During a family trip, my 2005 Fleetwood Discovery 39S threw code 168-1 for low ECM battery voltage and went into full shutdown mode—is this dangerous with kids onboard? Engine cut out, transmission selector went dark, ABS warnings everywhere - the whole nine yards. Scared the heck out of me when it happened on the interstate!

I'm seeing this seems to be a thing with these diesel pushers, but I'm drowning in conflicting info online. Some say it's the chassis battery, others blame alternator issues, and I've even seen posts about ECM power supply problems on the Caterpillar engines. What's the actual step-by-step process to track this down? And more importantly, how do I fix it so it doesn't leave me stranded again? Really need a complete walkthrough of what causes this code and the proper repair approach. …more

Best Cummins 6.7 Scan Tools for RV Diesel Diagnosis & DPF Regen (2024

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 Tire Age Limits: Why Replace Michelin Tires After 7 Years Despite Good Tread

Called three different tire shops this month about my 2020 Newmar Ventana's Michelin 275/70R22.5 tires and all want them replaced just for being 6 years old despite perfect tread. I'm meticulous about tire maintenance - I check air pressure religiously before and after every trip, whether it's a short weekend getaway or an extended cross-country journey like the 5000-mile trip I just completed.

Despite my careful maintenance routine, I experienced a blowout on the right rear inside tire during the final leg of that recent long trip. When the roadside service technician came out to help, he recommended replacing all six tires specifically because of their age, even though the remaining tires still have plenty of tread depth and appear to be in excellent condition visually.

This has me confused because I've heard conflicting advice from other RV owners - some say well-maintained motorhome tires can safely last up to 10 years, while others insist on much shorter replacement intervals. I'm trying to understand what the actual safety guidelines are for RV tire replacement based on age versus tread wear. Should I really replace tires that still look good just because of when they were manufactured? What's the real story on how tire age affects safety, and how do I properly check the manufacturing date to make this decision? …more

RV MPPT Solar Controller E1 Error Code: Causes & Fixes

Halfway through troubleshooting my MPPT solar charge controller's E1 error — would this be covered under warranty, or am I stuck paying out-of-pocket? The controller was working fine for months, but now it's completely stopped charging my batteries and just displays this E1 fault code on the screen.

From what I've read, this could be related to battery over-voltage conditions or possibly some kind of wiring fault, but I want to make sure I understand all the potential causes before I start troubleshooting. I'm comfortable doing basic electrical work myself, but I also want to know when this might be something that requires professional attention for safety reasons.

Can someone provide a detailed breakdown of what the E1 error specifically indicates, walk me through the proper diagnostic steps to identify the root cause, and explain the repair process? I'd especially appreciate guidance on how to safely approach this troubleshooting and what warning signs would indicate I should call in an expert instead of attempting the fix myself. …more

How to Upgrade Your RV Converter Charger for Lithium Batteries with Gentle Care

Halfway through planning our three-week cross-country trip next month, I realized my PD4560 60-amp converter/charger won't properly handle the lithium batteries I'm installing. My existing Progressive Dynamics unit obviously isn't designed for LiFePO4 batteries - I can use boost mode to charge them up, but I know that's not ideal for battery longevity.

I just purchased a 30 amp generator and I'm wondering if it will have enough capacity to handle not just my current charger, but potentially a larger lithium-compatible unit. I'm considering upgrading to a 75 or even 90 amp charger to reduce charging times, but I need to make sure my generator can handle the load. I'm trying to figure out the actual AC amp draw of these higher-capacity chargers and whether my 30 amp generator will be sufficient.

What are the best lithium-compatible converter/charger options that would work with my generator setup, and how do I properly size the charger capacity to match my lithium battery bank? …more

Ford F53 Motorhome Key Programming Guide: Security Features & Programming Tips

Apparently my 2008 Ford F53 motorhome is 16 years old and starting to have key programming issues — should I attempt DIY programming or call a locksmith? I just dropped $176 on two new transponder keys for my 2024 Windsport 34R (2022 F53 chassis) because I only had one set and didn't want to get locked out in the middle of nowhere wearing my pajamas and fuzzy slippers (again).

The Ford dealer quoted me another $140-170 to program these fancy chip keys, insisting I'd need to haul my 35-foot house-on-wheels down there for the programming. But the parts guy said "try them first" - and wouldn't you know it, both keys fired right up without any programming!

So what's the deal here? Are these unprogrammed transponder keys going to mysteriously stop working next Tuesday? Did I just dodge a bullet, or am I missing out on some important anti-theft features that actually matter? I'm feeling pretty smug about saving that programming fee, but also slightly paranoid that my motorhome might strand me at the worst possible moment! …more

Ford F53 V10 RV Chassis Repair Shops Near Raleigh NC - Engine Service

My Ford F53 V10 is showing misfire codes P0301 and P0303, but my compression test reads 180 PSI when everything says it should be around 150 PSI. I'm located near Raleigh, North Carolina, and I need to get some mechanical work done - specifically repairs to the exhaust manifold bolts and air conditioning system work.

The problem I'm running into is that when I call Ford dealerships in the area, they keep telling me they don't work on motorhomes, even though it's a Ford chassis. This seems crazy to me since the engine and drivetrain components should be the same as other Ford vehicles. The exhaust manifold issue and AC problems are fairly standard automotive repairs, so I don't understand why the Ford connection isn't helping me here.

What type of repair facilities should I be looking for instead? Are there specific shops or service centers near Raleigh that specialize in F53 chassis work, or should I be approaching this differently? I just need somewhere that can competently handle these mechanical repairs on my motorhome without the runaround. …more

Fleetwood Excursion Tire Upgrade Guide: 255 to 275 Width Conversion

After upgrading my 2015 Fleetwood Excursion M-35B from 255 to 275 width tires, it started getting sketchy handling on highway turns. The current 255/70R22.5 tires are wearing out and I'd love to go wider with 275/70R22.5 for better stability, but I keep getting conflicting advice from different tire shops.

Some say it's fine, others warn about clearance issues and potential problems. I really need to know what specific measurements I should check before making this change. What wheel width do I need? How do I verify there's enough steering clearance? I don't want to buy expensive tires only to find out they don't fit properly or aren't safe for my RV's load requirements. …more

How to Add Coleman Mach Heat Strips to RV AC Unit - Heat-Ready Control Box Installation Guide

Tried running my RV's electric heating this winter but it's eating through power way faster than it should, so I'm looking at adding Coleman Mach heat strips. I have a SportTrek Touring 272VRK with two AC units (Coleman-Mach 13.5k BTU and 15k BTU, models 48203-069 and 48204-069) with Cool-Only Control Boxes (model 8330-752) and I'm considering adding Coleman Mach electric heat strips, but I'm worried about a few things.

First, I'm concerned about whether my current AC units are compatible with heat strips - specifically the Coleman Mach 37203-4551 Electric Heat Kit/Strip. I want to confirm this will work with my existing 8330-752 control boxes. Second, I'm worried about the electrical load - I keep reading about heat strips drawing a lot of power and I'm scared of overloading my system or tripping breakers.

Most importantly, I absolutely do NOT want to lose the ability to use my existing Suburban SF-30FQ 30,000 BTU propane furnace - it's my primary heat source and I need that independence. I currently have 9420a381 digital thermostats controlling these systems, and I want to ensure I can maintain my current setup.

Is there a way to safely add Coleman Mach heat strips using some kind of Heat-Ready Control Box without compromising my furnace operation? I just want some reassurance that this can be done properly without creating problems. …more

Dometic R31 Stove Review + Gas Pressure Test Guide

Walked into my RV this morning to find my Dometic R31 stove flames randomly dying again - probably a dumb question, but is this normal? I've been looking at the Dometic R31 as a potential replacement, but I want to make sure I'm making the right choice before spending the money.

What's really concerning me is this gas pressure test mentioned in the installation manual. It talks about connecting some kind of gauge to a test port on the regulator, but doesn't specify what type of gauge or what pressure readings I should expect. I'm pretty handy with basic repairs, but gas systems make me nervous and I want to do this safely. Has anyone actually done this test, and is the R31 reliable enough to justify the upgrade from my problematic Wedgewood? …more

Ford V-10 Misfire Codes P0305 & P0307: Complete RV Engine Repair Guide for Motorhomes

Turned my compression tester on cylinders 5 and 7 and got 150 PSI readings, but I'm still pulling P0305 and P0307 misfire codes on my 2001 Ford E350 V-10. The engine runs smoothly overall, but the diagnostic codes are persistent.

I have replacement spark plugs and ignition coils available but want to ensure I'm following the proper troubleshooting sequence before investing time and effort. What is the recommended diagnostic approach for simultaneous misfires on cylinders 5 and 7?

Given that multiple cylinders are affected, should I prioritize certain components over others, or is there a systematic order that typically yields the most efficient resolution for this engine configuration? …more
