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 Battery Disconnect Switch Guide: When to Use, What Loses Power & Staying Safe

Wondering if I can skip the $400 shop diagnosis for my electrical issues and just figure out this battery disconnect switch myself, even though I'm getting conflicting advice.

Specifically, I'm concerned about what happens to things like my LP gas detector, carbon monoxide alarm, and refrigerator when I disconnect the battery. Will I lose all my radio presets and clock settings? Are there certain situations where I absolutely shouldn't use the disconnect switch?

I want to use it for storage to prevent battery drain, but I'm also wondering about daily use scenarios. What are the best practices to avoid any problems or safety issues? I really don't want to mess anything up or put my family at risk. …more

Dometic RV Furnace Runs 10 Seconds Then Shuts Off - Complete Troubleshooting Guide

The YouTube tutorials I followed to fix my Dometic DFMD35111 furnace that runs 10 seconds then dies actually made it worse—now it won't even start! Every time I try to run it, the same thing happens - it fires up, runs for exactly 10 seconds, then just shuts off completely. This has been going on for weeks now and I'm getting desperate since the weather is getting colder.

I've been trying to troubleshoot this myself but honestly don't know where to start. I can hear the blower running and the unit seems to ignite initially, but then it just dies. Is this a common problem with these Dometic units? I'm really hoping this is something I can fix myself rather than having to call out an expensive repair tech.

What are the most likely culprits when a furnace runs for just 10 seconds then shuts down? I need to know what components to check first before I start taking things apart. …more

Independent Super C Motorhome Manufacturers: Complete Guide to Non-Thor Builders

Three months of shopping and my wife just pointed out every Super C we're considering comes from Thor subsidiaries, making me realize consolidation might be trapping us with limited service options. It seems like Thor Industries and Berkshire Hathaway own practically every major motorhome brand out there now.

Before I make what could be a costly mistake, I need to know - are there actually any independent Super C manufacturers left that aren't owned by these corporate giants? I'm cautious about putting all my eggs in one basket with these mega-corporations. Should I even care about the ownership structure, or am I overthinking this? I just want to make sure I have options and aren't setting myself up for problems down the road. …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
RV Model Year vs Chassis Year: Understanding the Difference (It's Normal)

RV Model Year vs Chassis Year: Understanding the Difference (It's Normal)

This is my first RV and the title says 2019 but the chassis paperwork shows 2018 - something feels off here. I bought what I thought was a 2024 Tiffin Allegro Open Road, but when I got home and went to register it, the VIN shows it has a 2022 Ford chassis. The DMV registered it as a 2022, which means I've instantly lost two years of value!

I'm trying to figure out if this is normal in the RV industry or if I got taken advantage of. The dealer sold it as a 2024 model, but now I'm wondering if this kind of mismatch between the RV model year and the actual chassis year is standard practice. I've invested a lot in this RV and really hope there's a reasonable explanation for this discrepancy.

Can anyone explain if it's typical for RV manufacturers to use older chassis for newer model year RVs? I want to understand if this is legitimate or if I should be concerned about deceptive practices. …more

How to Replace Obsolete F53 Chassis ABS Control Module - Ford Discontinued Repairs Guide

How to Replace Obsolete F53 Chassis ABS Control Module - Ford Discontinued Repairs Guide

Last week my 2013 Coachman Encounter's F53 chassis started throwing ABS codes — can't afford the $3,000+ dealer quote so is there a DIY fix under $500? Our ABS control module failed, creating a no brakes issue. After being towed to a Ford Dealership on May 28th, the repair has been incredibly complex. They've received incorrect and damaged modules, and even after claiming to fix it, the ABS warning light remains on and reprogramming attempts have failed.

Ford apparently no longer makes this module for units over 10 years old. What alternatives exist for finding a compatible ABS control module for my older F53 chassis when OEM replacement isn't available? …more

Complete RV Solar System Guide 2024: Sizing, Installation & Wiring

Turned to YouTube for RV solar advice and now I'm more confused than ever - probably a dumb question, but how do I actually size this thing? Could fellow RV owners share details about their current solar setups?

- Total system watts
- Fixed or portable panels
- Rigid or flexible panel types
- Series or parallel wiring configuration
- Total system amps
- System voltage
- Wire gauge used

Coleman Mach AC Leaking Water Inside RV: Complete Troubleshooting Guide to Stop Drips

I'm planning my weekend getaway when I spotted water dripping from my Coleman Mach air conditioner model 49003A879 that definitely wasn't there yesterday. I'm in Myrtle Beach, with super humid conditions (90s with crazy humidity) and getting pea-sized water drops falling from the ceiling vents at maybe 2 drops per minute, which doesn't sound like much but it's making puddles on my floor.

I've been keeping the main ceiling vents mostly closed to push more air to the back of the coach. Climbed up on the roof expecting to find some fancy drain pump or tubing system, but honestly don't see much of anything obvious.

Is this just how these Coleman units work, or am I missing something? Really hoping this isn't a 'deal with it' situation, but wondering if my closed vents are screwing up the airflow or if there's actually a drainage problem I need to fix. …more

Tiffin Allegro Bus vs Newmar: Complete Owner's Comparison Guide

Finally decided to stop watching YouTube comparisons between Tiffin Allegro Bus and Newmar coaches since every reviewer contradicts each other and I'm more confused than ever. I've been researching for months and keep going in circles. Currently own a 2019 Tiffin Allegro Bus 40ip and absolutely love it, but we're looking to upgrade to a 45-footer and suddenly questioning everything.

Everyone says both Tiffin and Newmar are top-tier quality, but I need to understand the real differences. What makes each brand stand out? Is Tiffin's customer service really that much better, or is it just hype? Are Newmar's interiors actually more luxurious, or is that just marketing?

I've read every forum post and review I can find, but I really need someone to break down the key differences so I can make a decision and move forward. We're not buying new, looking at newer used models, but this choice is keeping me up at night! …more

HWH RV Slide Hydraulic Hose Repair: Complete DIY Guide

Replaced my HWH slide's hydraulic hose last month and now it's spraying fluid everywhere again with our three-week cross-country trip starting Friday! My 2007 Monaco Dynasty with HWH hydraulic system decided to throw me a curveball when the bedroom slide hydraulic line (1/4" I.D.) decided to spring a leak. After some detective work (and a lovely puddle of ATF to mark the spot), I traced it back to where a 1" air line to the front caliper had been playing the world's slowest game of 'saw through the hydraulic hose' for who knows how many miles.

I temporarily patched with Gorilla Tape and 1/2" hose clamps, which got the slide almost closed but still creeping. I'm planning to fix this with a compression coupling since that seems like the most straightforward approach for a DIY repair. Two quick questions: Can anyone confirm the 1/4" I.D. hose size for HWH systems? And once I get this coupling installed, will I need to bleed the system, or does it sort itself out? I'm hoping this repair goes smoother than my attempts to explain to my spouse why we're currently camping with a slide that's permanently 'almost' closed! …more

Tiffin Phaeton Atwood Levelegs Won't Fill Airbags: Troubleshooting Guide

Around 85°F, my 2008 Tiffin Phaeton with Atwood Levelegs refuses to fill the airbags for leveling — works perfectly in cooler weather. The coach is sitting low and I can't get it to fill the airbags properly. One of my leveling jacks isn't working right now.

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
