Newmar Motorhome Rough Ride Fix: Suspension & Air Pressure

Noticed my 2013 Newmar still rides incredibly rough through every crack and pothole even after replacing all six air bags. The ride height was never adjusted after the air bag replacement, and I'm worried I might be causing more damage or creating a safety hazard.

I upgraded from a Super C expecting a much smoother ride with the air suspension system, but this feels just as jarring. Am I missing something critical with the suspension setup? Could improper air pressure or ride height settings be causing this rough ride, and what other components should I be concerned about? I don't want to make things worse by continuing to drive it if there's a fundamental issue I'm overlooking. …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

Power Gear Leveler Won't Retract: Complete Repair Guide

Called Power Gear support and they said press retract after leveling, but my system deployed perfectly and now just sits there doing absolutely nothing. The system appears to receive the retract command since I can hear some activity, but the legs remain extended. The only way to get them up is by engaging the transmission which triggers the emergency retract function.

I need a systematic approach to diagnose this retraction failure. What are the most likely causes when Power Gear levelers deploy normally but won't respond to the retract command, and what's the proper troubleshooting sequence to identify whether it's a solenoid valve issue, wiring problem, or control module failure? …more

Monaco Diplomat Rear Air Suspension Won't Dump Fully - Troubleshooting Guide

Last week my 2006 Monaco Diplomat's rear air bags started refusing to dump all the way down when I hit the air dump before leveling. The front dumps fine, but the back stays partially inflated.

I'm still pretty new to RV maintenance and not sure where to start troubleshooting this. Should I be hearing air escaping when I activate the dump? What are the most common causes when rear air bags won't dump completely? Any guidance on what to check would be really appreciated! …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.

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

How to Test RV Door Magnetic Switch - Electric Steps Fix

Three steps this morning to my RV and noticed my electric steps weren't extending like they did perfectly fine yesterday. I've already verified that I have 12VDC at the 4-pin connector, and I even tried swapping in a different control module, but still nothing happens when I open the door.

Everything points to the door magnetic switch being the issue, but I'm honestly nervous about testing electrical components - I don't want to damage anything or create a safety hazard. Is there a safe way to test the magnetic switch with a multimeter? I want to make sure I'm doing this right before I start poking around with test leads. …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

Furrion FMCM15-SS Microwave Parts & Repair Guide - Complete Replacement Guide

Called three RV repair shops about my dead Furrion FMCM15-SS microwave and they all want $200+ — any DIY fixes for under $50? 🤦‍♂️

I'm trying to track down replacement parts but I'm having about as much luck as finding a level campsite during peak season. Does anyone know the best places to source parts for this model? I'm particularly wondering about common failure items like door latches and turntable motors - seems like these microwaves have their favorite ways to quit on us! …more

RV Awning Won't Extend or Retract: Complete Troubleshooting & Repair Guide

This power awning manual says hold the extend button for 3 seconds, but mine's completely dead and won't budge no matter how long I hold it. When I hit the extend button, it moves out maybe 6-8 inches and then immediately retracts on its own. I have to turn the power switch off and back on each time to get even that little bit of movement.

I'm hesitant to keep forcing it since I don't want to burn out the motor or make whatever's wrong even worse. Could this be an electrical issue with low voltage, or maybe the tracks are too dirty? I've also heard about limit switches causing problems but I'm not sure how to check those safely.

What are the most common causes when an awning does this short extend-then-retract cycle? I want to start with the safest troubleshooting steps before calling a repair shop. …more

How to Protect Your RV Alternator When Charging Lithium Batteries: DC-

Tried everything my neighbor did to charge his LiFePO4 batteries but mine keeps frying the alternator while his works flawlessly — what's different? I want to install a temperature sensing device that can interrupt charging by opening the solenoid between chassis and house charging systems if the alternator gets too hot. I'm looking to spec out components and understand the installation process, and I'm open to hearing why this might not be a good approach. My goal is preventing alternator overheating when these lithium batteries draw high current compared to my old flooded or AGM batteries. I'm looking for technical feedback and am totally open to critique. …more

Ford F53 RV Chassis: All Headlights Out - Complete Diagnosis & Repair

Pulled out my multimeter on this dead F53 headlight situation and I'm getting 12.4V at the relay when every Ford manual says it should read 12.6V. My 1999 Mountain High Pinnacle Class A with 76,000 miles on a Ford F-53 chassis has me stumped - ALL four headlights (both high and low beams) just went completely dead, but here's the weird part: every single other light works perfectly. Taillights, brake lights, turn signals, markers - they're all fine.

When the headlight switch is on, there are no headlights at all, and the blue high beam indicator remains constantly lit. I noticed a strange clicking sound from under the hood about every 20-25 seconds, which continued even after disconnecting the coach and chassis batteries.

I've already replaced the headlight switch thinking that was the culprit, but the same problem persists. No headlights whatsoever when I flip the switch, whether I'm on high or low beam. I'm starting to think it might be the combination switch or maybe a relay with a potential dead short, but I don't want to start throwing parts at this thing without some guidance.

Has anyone dealt with this exact scenario on a late 90s Ford chassis? What should I be checking first? I really need to get this sorted out before my next trip. …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?
