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

Dometic RV AC Not Cooling? 5 Common Fixes for Air Conditioner Troubleshooting Guide

Walked out to my RV this morning trying to decide between calling a repair tech or troubleshooting my Dometic Brisk Air rooftop AC myself since it's showing weird operational issues. The compressor engages and fan motor operates normally, but the unit fails to produce cold air output. Temperature differential across the evaporator coil is minimal.

Unit functioned properly through previous cooling season with no apparent issues. Current symptoms include normal airflow volume but inadequate cooling capacity. What systematic diagnostic procedure should I follow to identify the root cause? Looking for a methodical troubleshooting sequence that addresses the most probable failure points in order of likelihood. …more

Ford V10 RV Chassis A/C Cycling On and Off at High RPM - Complete Fix

Before highway driving yesterday, my gauge showed 250 PSI on the high side, but every Ford V10 manual says my 2019 Georgetown XL should max at 200 PSI. After completing full refrigerant system service including line replacement, receiver-drier, and expansion valve replacement, followed by proper evacuation and R134a charge to specification (920g), the system operates normally at idle and low RPM conditions.

However, above 2800 RPM during highway driving, the compressor cycles on and off repeatedly. System pressures appear normal during stationary testing. Is this cycling behavior a designed protective feature of the Ford V10 PCM during high load conditions, or does this indicate an underlying issue with head pressure, airflow, or refrigerant charge that requires further diagnosis? …more

RV Water Pump Running But No Water? Complete Troubleshooting Guide 202

Finally looking at my RV water pump right now and it's running constantly but there's absolutely zero water coming out of any faucets. However, when activating any fixture throughout the system, the water pump initiates and runs continuously without producing water flow at any outlet point.

All system components appear to be functioning mechanically - pump motor engages properly, electrical connections are secure, and there are no visible leaks in accessible plumbing runs. The symptom manifests uniformly across all water delivery points including kitchen, bathroom, and exterior service connections.

What diagnostic steps should be performed to identify the root cause of this no-flow condition despite continuous pump operation? …more

How to Fix Dutch Star Front Air Bags That Won't Inflate - Height Valve Troubleshooting

I replaced my 2006 Dutch Star height valve but the front air bags still won't inflate, the valve seems stuck, AND the whole front end is sitting way too low. The air pressure gauges look totally normal, but when I try to air up the front bags, they just won't fill up. Instead I'm hearing this whining noise and air is literally coming out of the height control valve exhaust port.

It's like the system thinks something's wrong but I can't figure out what. The bags themselves seem fine, and there's definitely air pressure in the system. What would cause the height valve to dump air instead of letting the bags inflate? This is driving me nuts! …more

Ford F53 V10 Bypass Oil Filter Installation: Best Mounting Locations for RV Chassis

Walked out to check my oil analysis results and they're showing 15-micron contaminants, but everything says my 2003 F53 V10's factory filter catches down to 25 microns. I've been reading about how these can help extend oil life and keep things cleaner, but I'm honestly not sure where the best place to mount one would be.

I've seen some people mention sandwich adapters at the original filter location, remote mounting blocks, and even tapping directly into the engine block. As someone who's still learning, I don't want to mess this up or create problems down the road. What's considered the best practice for mounting location on the F53 V10? I'd really appreciate some guidance from those who have done this before. …more

Onan 5500 Generator Tune-Up Guide: Best Aftermarket Parts & Filters 20

Before my last camping trip when I tried to order replacement parts, I discovered that finding genuine OEM components for my Onan 5500 generator has become nearly impossible. The Cummins website has been showing most tune-up components as out of stock for months now, and when I do find supposedly "official" Onan oil filters online, many retailers are substituting generic filters that may not meet the same specifications.

I've been researching alternatives and I'm particularly concerned about getting the right oil filter and spark plugs. For the oil filter, I've seen conflicting information about whether aftermarket options like Wix filters are truly compatible - some sources mention the 57398 but I've read mixed reviews about fitment issues. For spark plugs, my current ones are NGK BPR4EY, and I've heard the NGK 3432 might be equivalent, but I want to make sure before ordering.

I'm also planning to stick with zinc-containing oil like Rotella T6 15w40 since I know air-cooled engines need the extra protection, but I'd love confirmation that I'm on the right track with quality aftermarket parts that won't compromise my generator's performance. What specific part numbers and brands would you recommend for a reliable tune-up when OEM parts aren't available? …more

60 PSI Water Pressure in RV: Is It Too High? (Expert Guide)

Found myself staring at my water pressure gauge right now and there's 60 PSI showing even though my regulator is preset to 50 PSI. This is the first time I've used this particular gauge (bought it about 6 months ago), and it immediately shot up to 60 with no way to adjust it down.

Is 60 PSI going to damage my RV's plumbing system? I'm worried because that seems high, but I'm not sure if it's actually dangerous or just at the upper limit. Could my regulator be failing, or might this new gauge be giving me a bad reading? I'm planning a trip to get a replacement tomorrow, but I want to make sure I'm addressing the right problem here. …more

Ford F53 RV Fuel Pump Problems: Why They Fail & How to Fix Them Permanently

Got a neighbor with a 2007 Ford F53 motorhome that runs flawlessly while my 6.8L keeps burning through fuel pumps — what's his secret? The fuel pump has failed THREE times in just four years, and I'm scared there's something seriously wrong that's not being diagnosed properly. Each time the dealer just replaces the pump and says everything looks fine, but this can't be normal, right?

I'm starting to wonder if I'm doing something wrong with storage or if there's an electrical problem that's killing these pumps. The last thing I want is to get stranded somewhere dangerous because of another failure. Should I be worried about contaminated fuel? Could my storage practices be causing this? I really need to understand what's actually causing these repeated failures before I spend more money just replacing pumps that are going to fail again. …more

4R100 Transmission Temperature Gauge Sender Location Guide for RV Owners & Mechanics

Despite my RV mechanic insisting I need a completely new 4R100 transmission for overheating, shouldn't I install a temperature gauge first to verify what's really going on? I can't seem to find any factory temperature sender on this transmission - am I missing something obvious?

I'm nervous about drilling into the pan or tapping into lines since I don't want to create leaks or cause more problems than I'm trying to solve. Is there a safe, proven way to monitor transmission temperature on a 4R100 without risking damage? I've heard about electronic options too but not sure if they're reliable. …more

Torque Pro App Review: Complete RV Engine Monitoring with OBD2 Diagnostic Tool

The previous owner of this used RV left me completely in the dark about monitoring what's actually happening with the engine! I recently bought an OBD Link adapter and an Amazon Fire tablet specifically to use the Torque Pro app for engine monitoring. I'm pretty much a caveman when it comes to technology, and I'm currently stuck trying to figure out how to set up the dashboard.

I keep hearing horror stories about transmission temps and engine issues that could have been caught early with proper monitoring. Problem is, I have no clue how to actually configure the app to show me useful data. Anyone have tips for getting the Torque Pro dashboard set up for someone who's totally tech-challenged? Bonus points if you can help me understand how to get meaningful information without wanting to throw my device out the window! …more

How to Find the Correct Tire Pressure for Goodyear Fuel Max RSA RV Tires

Before, my old Class C worked fine with the dealer's generic tire pressure chart — but these new Goodyear Fuel Max RSA 245/70R19.5 load range H tires on my 2008 Winnebago Sightseer 29R are completely different. My loaded RV weighs 6,020 lbs on the front axle and 11,220 lbs on the rear axle based on my most recent scale weights.

I'm concerned that 100 PSI might be too high since my previous Goodyear G670RV tires ran fine at 85-90 PSI, and the handling feels different now, especially when towing. I want to make sure I'm running the correct tire pressure based on my actual axle weights rather than just using maximum ratings or generic guidelines. What's the proper way to determine the right inflation pressure for these Fuel Max RSA tires given my specific load conditions? …more

RV Spare Tire Check: Verify Size and Pressure Before Every Trip

Every time I crawl under my Class C RV I stare at that spare tire that's been hanging there for years collecting road grime — check or replace? I mean, it's there in the compartment looking all tire-like, but I'm wondering if there's stuff I should be checking?

I keep hearing horror stories about people getting stranded because their spare was useless when they actually needed it. Turns out this happened to me - I discovered my spare was the wrong size (245 75R16 instead of 225 75R16), which could have been a major problem during a blowout.

What's the smart move here for spare tire maintenance? I learned to check not just the tire size, but also the air pressure. Mine was sitting at just 58psi, which thankfully I could fix with my air compressor.

I'd hate to be that person calling for help on the side of the highway! Anyone else have similar experiences? …more

RV Gray Tank Draining Slowly? Fix Clogs & Flow Issues

Called around to shops about my 2019 Forest River Cherokee's gray tank drain crawling—what used to take 5-10 minutes now drags on for 30-45 minutes. The black tank still drains at normal speed, so I don't think it's a problem with the main sewer connection or hose.

I'm wondering what typically causes gray tanks to develop drainage problems over time. We do a lot of dishwashing in the RV and I'm thinking maybe grease or soap buildup could be creating blockages somewhere in the system. The flow starts out okay but quickly reduces to just a trickle, even though I know there's still plenty of water in the tank.

What are the most common culprits behind slow gray tank drainage, and what's the best approach for diagnosing and fixing these flow issues? I'd rather understand the root causes and proper solutions before I start taking things apart or using harsh chemicals that might damage the system. …more
