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.

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

Remote RV Diesel Fueling: Complete Guide for Campground Fuel Strategies

Last night at 11 PM I'm staring at my diesel RV's fuel gauge showing nearly empty — need to figure out remote campground fuel strategies before we head out this morning. With a 5 gallon Harbor Freight stick transfer pump, I've been able to add fuel when truck stops aren't convenient, but I'm concerned about static electricity risks.

My current setup involves using the pump to transfer diesel with the fuel can on a camping table, since my RV's fuel inlet is located under a slide. I pumped 10 gallons successfully, but I'm wondering about the safety of this method.

I know there are static electricity concerns when transferring fuel, and I'm curious about the specific risks with diesel. How safe is it to transfer fuel when the can isn't directly grounded to concrete? Are there best practices I should follow when manually adding diesel in remote locations? …more

RV Tire Age Limits: Why Replace Michelin Tires After 7 Years Despite Good Tread

Called three different tire shops this month about my 2020 Newmar Ventana's Michelin 275/70R22.5 tires and all want them replaced just for being 6 years old despite perfect tread. I'm meticulous about tire maintenance - I check air pressure religiously before and after every trip, whether it's a short weekend getaway or an extended cross-country journey like the 5000-mile trip I just completed.

Despite my careful maintenance routine, I experienced a blowout on the right rear inside tire during the final leg of that recent long trip. When the roadside service technician came out to help, he recommended replacing all six tires specifically because of their age, even though the remaining tires still have plenty of tread depth and appear to be in excellent condition visually.

This has me confused because I've heard conflicting advice from other RV owners - some say well-maintained motorhome tires can safely last up to 10 years, while others insist on much shorter replacement intervals. I'm trying to understand what the actual safety guidelines are for RV tire replacement based on age versus tread wear. Should I really replace tires that still look good just because of when they were manufactured? What's the real story on how tire age affects safety, and how do I properly check the manufacturing date to make this decision? …more

RV LP Gas Detector False Alarms: Complete Troubleshooting Guide

Already tried everything but my RV's LP gas detector has false alarms in the garage, keeps beeping at random times, AND won't reset properly. Even with the LP tank completely shut off, the alarm still goes off within hours. It's located in the bottom of the fridge cabinet.

I've checked everywhere for actual leaks - can't smell anything, and all my appliances still light immediately when I take the RV out. The detector seems fine outside but becomes a nightmare indoors. I'm wondering if it's the sensor going bad, poor placement, or if there are other things that can trigger these detectors besides actual propane leaks?

I really need a complete breakdown of what causes these false alarms and how to fix this issue once and for all. Should I be looking at replacing the detector entirely, or are there troubleshooting steps I'm missing? …more

RV Refrigerator Ammonia Smell: Leak Repair & Safety Guide

Last spring when I opened up my RV for the first camping trip, that same overwhelming ammonia stench hit me the moment I cracked open the refrigerator door. It seems to be getting worse and I can smell it throughout the coach now. I'm scared this might be some kind of refrigerant leak but I'm not sure.

Is it safe to keep using the refrigerator? Should I be concerned about health risks from breathing this in? I don't want to make the situation worse or put my family in danger. What should I do immediately to stay safe? …more

Ford F53 V10 RV Chassis Repair Shops Near Raleigh NC - Engine Service

My Ford F53 V10 is showing misfire codes P0301 and P0303, but my compression test reads 180 PSI when everything says it should be around 150 PSI. I'm located near Raleigh, North Carolina, and I need to get some mechanical work done - specifically repairs to the exhaust manifold bolts and air conditioning system work.

The problem I'm running into is that when I call Ford dealerships in the area, they keep telling me they don't work on motorhomes, even though it's a Ford chassis. This seems crazy to me since the engine and drivetrain components should be the same as other Ford vehicles. The exhaust manifold issue and AC problems are fairly standard automotive repairs, so I don't understand why the Ford connection isn't helping me here.

What type of repair facilities should I be looking for instead? Are there specific shops or service centers near Raleigh that specialize in F53 chassis work, or should I be approaching this differently? I just need somewhere that can competently handle these mechanical repairs on my motorhome without the runaround. …more

Ford F53 Chassis Firewall Wiring: Finding Brake LED Through-Holes

Opened up my 2022 Holiday Rambler 36DB for spring prep and once again I'm staring at my 2021 Ford F53 chassis firewall wondering where those brake LED through-holes are hiding. I need to run the brake indicator LED wire from my toad to the dashboard inside the motorhome, but I'm having trouble locating the best firewall penetration point.

Rather than drilling a new hole through the firewall (which I'd prefer to avoid for obvious reasons), I'm hoping to find an existing through-hole or grommet that I can utilize. I've heard that Ford F53 chassis typically have several factory access points, but I'm not sure exactly where to look or which ones would be most suitable for this type of low-voltage wiring installation.

Can anyone provide specific guidance on where to find existing firewall through-holes on the F53 chassis that would work well for routing brake indicator wiring? I want to make sure I'm using an appropriate location that won't interfere with existing systems and will provide a clean, professional installation. …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

Onan 4000 Generator Won't Start Without Choke: Code 14 Troubleshooting Guide

Halfway through another camping trip and trying to decide between babying my Onan 4000 with manual choke every startup or finally fixing this Code 14 nightmare. Let me try again:

Just found out that my 2013 Thor Class C's Onan 4000 generator won't cooperate after sitting since March, and I'm dealing with a nightmare. Been getting Code 14 errors and spent half the morning just trying to get it fired up.

The only way I can get it started is by manually messing with what I think is the choke linkage - otherwise it just won't go. Once I shut it off, same story - won't restart unless I physically manipulate that linkage again. Only has 240 hours on it and was serviced about 2 years ago.

I'm pretty sure the carburetor is gummed up from sitting, but what exactly does Code 14 mean? And more importantly, what do I need to clean to get that choke working automatically again? I really need to get this thing running properly before our next trip! …more

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

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

5000 lb RV Hitch Rating Explained: Weight Limits, Tongue Weight & Safety Guide

According to my old Class C setup this same hitch rating confusion was easily solved with basic math — but towing a Jeep behind this Class A motorhome has me worried about weight limits and legal liability. After checking the Jeep website, I noticed that most Jeep models weigh over 5100 lbs, which seems to exceed typical 5000 lb hitch ratings. Could this potentially expose RV owners to liability if something goes wrong during towing? I want to understand the weight implications and safety considerations before hooking up a vehicle. Does this mean most Jeep owners towing with a gasser Class A might be inadvertently exceeding safe towing limits? …more
