Onan 5500 Generator Problems: Complete Repair Guide 2024

Spent three hours testing my 2014 Hurricane's Onan 5500 gen getting 11.8 volts output when every manual says it should be 12+ volts! Here's the weird part - when I disconnect the remote harness, the generator fires right up and purrs like a kitten. But the second I plug that remote connection back in, boom - both the remote start light AND the generator start light come on, and then... nothing. Won't start at all.

The really bizarre symptom is this chattering from the fuel pump when the remote is connected. I can literally feel the fuel line jumping around when I put my hand on it. It's like the pump is having some kind of seizure or something!

I'm guessing this has to be some kind of electrical issue between the control board and the remote system, but I've never seen anything quite like this before. Anyone dealt with this specific combo of symptoms on an Onan 5500? Really hoping there's a known fix because pulling this thing out of the RV again would be a major pain! …more

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

Generac 7.5kW Diesel Generator Repair Guide - RV Troubleshooting

Planning to ignore the weird noises from our Generac 7.5kW diesel generator backfired when my wife pointed out I definitely made things worse during my repair attempt. I have a 2007 Monaco with a Generac 7.5kW diesel generator, and yesterday when I tried starting it, the battery was really weak. I probably held the starter button too long - maybe 15 seconds or so - because it was cranking so slowly and I kept hoping it would catch.

Now when I try to start it, I just get a single click and nothing happens. I'm worried I damaged something by cranking it so long with that weak battery. Should I be looking at the starter solenoid or starter motor? Is there anything I can check myself before I have to take it to a repair shop? I'd really appreciate any guidance on troubleshooting this. …more

RV Sidewall Blistering & Delamination Repair Guide 2024

According to three different RV shops, fixing my bubbling sidewall delamination will cost thousands, but I'm wondering if tackling this DIY repair myself is actually feasible. My 2004 Itasca Sunova has decided to sprout some lovely blisters on the right sidewall - two beauties that are about 12-14 inches long and 3-4 inches wide, running vertically right behind the awning arm. Perfect timing since we're currently on the road living our best RV life!

I'm pretty sure water snuck in somewhere (probably from the roof rail or that shower skylight we never use), and now my RV looks like it's got chicken pox. Since we can't exactly pull into the nearest RV surgeon's office, I need to know: what can I do right now to stop this from getting worse, and what's involved in actually fixing this mess properly? I'm hoping there's some kind of emergency containment plan that doesn't involve duct tape and prayers! …more

RV Liquid Spring Adjustment Guide: Setup & Tuning Tips

Three different adjustment knobs on my 2022 Tiffin Open Road 34PA's LiquidSpring suspension and I'm staring at them with zero clue about the limits.

I've got LiquidSpring suspension on all four corners, but I'm specifically wondering about the rear struts. Can I raise and lower just the rear ones independently, or am I stuck adjusting everything at once like some kind of suspension caveman? I'd love to dial in the perfect ride height and handling, but I need to know if I can fine-tune the back end separately from the front. Between the control panel and what I assume is some fancy smartphone app, surely there's a way to make this old road warrior ride like a dream without turning into a mechanical engineer, right? …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

RC7-GS Inverter AGM Battery Settings: Complete Setup Guide

Replaced my 105Ah AGM battery and now my RC7-GS inverter charger is completely rejecting it like this capacity doesn't exist in its programming.

The charging settings only go from 125Ah up to 1000Ah, with an 'auto' option that supposedly 'learns' my battery but resets every time the low voltage cutoff trips (which feels like cheating, honestly). I'm worried about undercharging or cooking my expensive new AGMs if I pick the wrong setting.

Oh, and while we're talking about things that don't work as advertised - the generator auto-start feature might as well be a myth. Can't even manually start the generator from the RC7 panel. At this point I'm wondering if I should have just stuck with my old setup that actually worked! Anyone know what I'm doing wrong here? …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

Dometic 310 Toilet Leaking at Foot Pedal: Complete Fix Guide

Called my weekend camping trip short because my Dometic 310 toilet has water pooling underneath, the flush mechanism sticking, AND that annoying gurgling sound happening constantly. I can see the leak between the fixed outer part and the moving pivot section when the pedal is pressed.

Already replaced the toilet valve but it's still leaking from the same spot. The inlet and outlet hoses look fine. What causes leaks at the pedal mechanism itself after the valve has been changed? …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

How to Find Reliable RV Repair Shops: Expert Tips & Red Flags to Watch Out For

About every summer my 2004 Adventurer runs like a dream until temps hit 85°F, then it breaks down constantly and no shop can figure out why. The main slide out has been acting up with the HWH hydraulic system, and I honestly don't know enough to fix it myself.

I'm worried about getting taken advantage of since I don't really know what questions to ask or what warning signs to watch out for. I've heard horror stories about people paying huge bills for shoddy work. What's the best way to research and find a reliable shop? Are there specific things I should ask them before I commit to having work done?

Any guidance would be really appreciated - I just want to make sure I'm being smart about this and not walking into a bad situation. …more

How to Remove Firefly RV Control Panel: Complete DIY Guide (2024)

Our 2019 Fleetwood Discovery LXE has a malfunctioning Firefly multiplex control panel that needs to be completely removed. I've been putting this off for months because I keep hearing horror stories about people cracking their panels or damaging the surrounding woodwork during removal.

I need to access the back of the unit for some electrical work, but I'm honestly terrified of breaking something expensive. The panel seems to be mounted flush with no obvious screws or clips visible from the front. I've searched everywhere but can't find a complete walkthrough that covers the preparation, actual removal process, and how to get everything back together properly.

Can someone please provide a detailed DIY guide that covers all the steps? I'm willing to take my time and do this right - I just need to know the proper technique so I don't end up with a broken control panel or damaged wall. …more
