RV Water Pump Losing Prime: Troubleshooting & Winterization

Got a 2022 Tiffin Open Road 34PA with a water pump that keeps losing prime during winterization — about to buy a replacement but wondering if I'm throwing money at the wrong problem? I can get it back by quickly opening and closing one of the lowest drain valves, but then it just loses prime again after a while. This has happened on other RVs I've winterized too, but it's particularly stubborn on this Tiffin.

I'm suspecting it might be the inline check valve next to the pump or maybe the one behind the Truma hot water heater, but I'd love some guidance on proper diagnosis. What are the most common causes of prime loss during winterization, and what's the best way to troubleshoot and fix this? I want to make sure I'm covering all my bases for winter storage prep. …more

RV Electrical Problems: 12V & 120V Troubleshooting Guide 2024

Around $500 in parts later — replaced the main breaker, cleaned all connections, checked the transfer switch — my 2007 Holiday Rambler Admiral SE still won't recognize shore power.

I'm pretty sure 110V is making it to the rig since I can measure it, but somewhere between the plug and my appliances, something's not happy. Energy management panel is dark too. What's the logical troubleshooting order here? I keep hearing about transfer switches and breaker panels but honestly don't know where to start without making things worse! …more

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

RV Storage on Gravel: Preventing Weed and Moisture Issues

Nobody warned me that buying a house with RV storage meant inheriting the previous owner's 13-year-old weedy, muddy gravel disaster. While considering this location's storage options, I want to mitigate potential issues with weed growth and moisture retention under the RV.

I'm seeking advice on effective strategies for storing on a gravel surface that shows significant weed penetration and moisture retention. Initial ideas include pre-treatment herbicide application and installing a protective barrier, but I want input from experienced RV owners.

My primary concerns are preventing undercarriage damage and managing moisture/vegetation growth. I plan to spray weed killer beforehand and potentially lay down a weed barrier, pending facility approval. What techniques or materials do you recommend to protect my RV during storage? …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

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

Ford F53 7.5L RV Won't Start: Fuel Pump Relay Voltage Drop Fix

Woke up to my 1996 Ford F53 7.5L motorhome eating through my patience and wallet with this no-start issue that keeps coming back. It cranks strong but absolutely will not start, and I've been chasing this problem for weeks now. The engine ran fine for about 3-4 minutes one day, then just died and hasn't started since.

I've already done quite a bit of diagnostic work:
- Replaced PCM and distributor
- Fuel pump works when powered directly
- Battery is fully charged
- Checked fuses and relays
- PCM relay voltage drops from 12.2V to 9.3V with key on
- Fuel pump relay only shows 3.3V at pin 86 (should be 12V)
- Inertia switch tested at 1.7V at connector
- ANL 178 fusible link fluctuates between 0.3-0.6V

The engine will only start with starter fluid when the SPOUT is removed. I'm getting only 5.5V at the fuel pump connector.

Has anyone dealt with this specific issue on an F53 chassis? I really need to get this RV back on the road and I'm running out of ideas! …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

How to Replace RV Slide Topper Fabric: Complete DIY Guide 2024

I pulled into three different campsites this month and my torn slide topper is eating through my gear faster than I can replace it. I've never done anything like this before and I'm worried I might damage the whole mechanism or make things worse.

Can I actually replace just the fabric portion safely, or should I bite the bullet and have the entire assembly replaced by a professional? I'm also concerned about costs - I'm hoping this won't break the bank. If it is something I can do myself, how difficult is it really? I don't want to get in over my head and end up with a bigger problem than I started with.

Can you help me understand the best approach for my specific situation? …more

Kwikee RV Steps Not Working? Complete Troubleshooting Guide (2024)

Apparently we're leaving for a three-week cross-country trip next Monday and my Kwikee electric RV steps are still having intermittent retraction issues even after replacing both the gear box and motor. My steps are exhibiting intermittent retraction issues - they extend normally but require manual assistance to retract fully, stopping approximately a quarter inch through the cycle without intervention. I've already installed a new gear box and motor, yet the problem persists.

What systematic diagnostic approach should I follow to identify the root cause? I need to understand the complete troubleshooting sequence for motor functionality, electrical switch operation, and mechanical linkage components. Are there specific voltage measurements, resistance checks, or mechanical adjustments that should be performed to isolate whether this is an electrical or mechanical failure?

Thanks,

RV Grey Water Tank Clogged? 7 Proven Solutions to Clear Blockages Fast

Found out my RV service tech wants $800+ to replace the entire grey water system on my 2007 RV for an intermittent blockage that seems fixable. It doesn't seem to matter if we're level or not - it's completely random.

I've tried using a high suction shop vac and even attempted snaking it, but I'm nervous about forcing things and making the problem worse. I suspect it might be a manufacturing plug that fell into the tank, but I'm not sure. I found one solution with a reverse flush valve that seems to work temporarily, but I'm concerned about the underlying cause.

What are the safest and most proven methods to diagnose and fix these random grey water blockages? I don't want to damage the tank or create bigger problems, but this unpredictable draining is driving me crazy. Are there specific cleaning products or techniques that actually work without risking harm to the system? …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.
