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 Inverter Guide: Modified vs Pure Sine Wave - Safe Power

My multimeter's out and I'm ready to tackle this RV electrical mess myself — pretty sure the inverter's the culprit but need to know where to start. I have a 2000 Winnebago Ultimate Advantage with four deep cycle house batteries and recently installed a Xantrex 758 inverter to replace my old Freedom 15 unit. The first time I tried using the inverter power while unplugged from shore power, something very strange happened - a hair dryer in the bathroom started running by itself and wouldn't shut off when I tried the switch. I had to unplug it, and the handle was warm. The hair dryer appears to be ruined now.

When I bought the Xantrex 758, I paid around $725 for what I thought was a good unit, but I'm now learning there's a difference between modified sine wave and pure sine wave inverters. I wasn't aware of this distinction when I made the purchase, and it turns out the 758 is a modified sine wave unit. I've since heard that modern electronics, especially things like residential refrigerators, computers, and sensitive electronic components, can be damaged by modified sine wave power.

I'm really concerned about potentially damaging my new residential refrigerator, stereo system, and computer equipment. Should I be worried about using this modified sine wave inverter with modern RV electronics? Is the hair dryer incident a sign that I need to upgrade to a pure sine wave unit, or are there other factors that could have caused this problem? I'm trying to understand if my current setup is putting my expensive electronics at risk. …more

Michelin RV Tire Problems: Complete Guide & Solutions 2024

Standing in my driveway planning to tackle these serious handling issues with my new Michelin Agilis HD Z 245/70R19.5 tires on my 2018 Winnebago Vista LX 27N this Saturday — what should I check first? The RV now has 25k miles, and since switching from Goodyear tires, I'm experiencing terrible tail wag - especially when towing my 2024 Toyota Tacoma and in windy conditions.

I've tried multiple tire pressures (82 psi from door sticker, 110 psi from installer, up to 100 psi) but nothing resolves the side-to-side movement. I have several stability modifications installed (Rear Trac Bar, Aux Roadmaster Rear Swaybar, Front Roadmaster Swaybar, Koni FSD shocks), which previously helped with handling.

The movement feels like the towed truck is actually pushing the RV's rear side-to-side, making driving extremely uncomfortable. I'm within Michelin's 60-day/2500-mile buy-back period and want to understand why these tires are performing so differently from my previous set.

Could experienced RV owners help me diagnose what might be causing these handling problems? …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 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

Femco vs Fumoto Oil Drain Valves for RVs - Which is Better?

Looked at my mechanic's quote for a $300 professional oil change setup and something seems off—wouldn't a basic Femco or Fumoto drain valve work just fine? I've narrowed it down to Femco and Fumoto, but I'm genuinely worried about road debris damage since RVs sit lower and encounter more hazards than regular vehicles.

The thought of a drain valve getting hit by rocks or debris and causing a catastrophic oil leak on the highway keeps me up at night. I need to know which design is actually safer and more protected in RV applications. Does one have better protection features than the other? I'd rather be overly cautious than deal with a roadside emergency. …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

Ford V10 Triton Engine Maintenance Guide: EGR Delete vs Regular Service Tips

Spent years doing regular EGR maintenance on my old gas motorhome without issues — but this 2007 Fleetwood 31' Tioga with Ford V10 Triton has me second-guessing everything. I keep reading conflicting information about EGR delete procedures on V10 engines, and I'm worried I might make things worse if I mess with it.

Is the EGR delete modification actually necessary on this 2007 3-valve V10, or am I overthinking this? I don't want to void any warranties or create problems that weren't there before. Would I be better off just sticking to regular maintenance instead of modifications? I'm looking for reassurance that I'm taking the right approach to keep this engine running reliably for years to come. …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

RV Flat Tire on Highway: Emergency Steps & Specialized Roadside Service Tips

Every highway mile seems to be eating through my Tiffin Allegro motorhome tires way faster than it should, especially after that brutal double blowout on the back axle. When this happened to us, we found that regular AAA and typical roadside assistance don't always help with RVs. We were stranded and eventually had to use a service called Driving Solutions, who charged us $1600 for used tires after eight hours of waiting.

What's the proper procedure if this happens? Should I try to move to a safer location first, or stop immediately? Who should I call for help - are there specialized services that handle RV tires? I want to be prepared with the right contacts and know the safe steps to take, because I imagine regular tow trucks and tire services might not have the equipment or expertise to handle a large motorhome tire emergency on the interstate. …more

RV Slide-Out Maintenance: Complete Guide to Prevent Wear and Extend Lifespan

Before I even finish extending my 2018 Newmar 2702 slide-out, there's this grinding vibration that kicks in during the final positioning phase every single time. The motor works hardest during that last foot of travel when the slide settles into place.

This observation has me questioning optimal maintenance protocols for slide-out longevity. What are the most effective strategies for reducing mechanical wear on these systems? I'm particularly interested in understanding proper usage frequency, seal maintenance requirements, and whether partial extension during routine tasks like cleaning provides any protective benefits.

Looking for comprehensive guidance on preventive maintenance practices, lubrication schedules, and storage considerations that will maximize slide-out system lifespan while minimizing premature component failure. …more

RV Tire Replacement: When to Replace by Age - Complete 7 Year Rule Guide

Pulled into three different tire shops asking about RV tire replacement and got three completely different answers about when tires actually need replacing. The unit has six tires with 2018 DOT date codes, making them 7 years old as of 2025. Mileage is approximately 28,000 miles, and visual inspection shows good tread depth with no apparent cracking, bulging, or other visible deterioration.

A tire technician who performed my state inspection indicated the tires appear serviceable from an external assessment standpoint. However, I understand there may be internal degradation factors not visible during standard inspection procedures.

What is the technical consensus on replacement timing for RV tires when age limits are reached but visible condition remains acceptable? Specifically looking for guidance on the 6-7 year replacement interval and whether internal rubber compound deterioration poses legitimate safety risks regardless of external appearance. …more

Ford E-350 vs E-450 Chassis: RV Fuel Economy, Power & Weight Capacity

Last weekend I felt this awful engine strain and heard sluggish acceleration sounds while test-driving a 2017 Phoenix Cruiser #2351 with its E-350 chassis and V10 engine. I'll be doing extensive western touring through mountain and plains regions, which means substantial mountain grades and wind challenges. I'm comfortable driving slowly and want to understand two key things: 1) Will this E-350 chassis handle mountain grades without major issues, and 2) What's the real-world fuel consumption like? I plan to do an initial inspection this weekend, followed by a third-party mechanical review. I'm not overly concerned about fuel economy but want to understand the actual performance limitations. I'd appreciate insights from owners who have experience with similar touring conditions on an E-350 chassis. …more
