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

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

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

How to Reduce RV Interior Noise: Complete Sound Dampening Guide for Motorhomes

Despite having a 2021 Coachmen Mirada, looking at my sound meter right now and there's 69 decibels of highway noise blasting through the cabin. My target is to achieve approximately 65 decibels for better communication with passengers.

I need a systematic approach to interior noise reduction. What are the most effective sound dampening materials and techniques for motorhomes? Specifically, I'm looking for solutions that address engine noise transmission, road noise, and any rattling components that contribute to the overall sound level.

What realistic noise reduction can I expect from proper sound deadening implementation, and what are the key areas to focus on for maximum impact? …more

Ford F53 Motorhome Ride Quality: Improve Your Harsh Ride with Shocks &

I walked into my first Class A motorhome ownership with zero experience and my 2022 Jayco Precept Prestige 36H on an F53 chassis rides like I'm driving over constant speed bumps. This 3-year-old coach with 15,000 miles beats us to death on every interstate joint and bridge transition - it's honestly brutal and making long trips miserable. I've already added Sumos on the front and Timbrens on the rear, which helped somewhat with roll/sway, but I'm still getting hammered by road imperfections while blueoxing my Honda CRV.

I keep hearing conflicting advice about gas shocks versus other options, proper tire pressures, and suspension upgrades. What actually works to smooth out these bone-jarring impacts? I need real solutions that will make a noticeable difference in ride comfort, not just minor tweaks. Has anyone successfully tamed an F53's harsh ride? …more

Fleetwood Excursion Tire Upgrade Guide: 255 to 275 Width Conversion

After upgrading my 2015 Fleetwood Excursion M-35B from 255 to 275 width tires, it started getting sketchy handling on highway turns. The current 255/70R22.5 tires are wearing out and I'd love to go wider with 275/70R22.5 for better stability, but I keep getting conflicting advice from different tire shops.

Some say it's fine, others warn about clearance issues and potential problems. I really need to know what specific measurements I should check before making this change. What wheel width do I need? How do I verify there's enough steering clearance? I don't want to buy expensive tires only to find out they don't fit properly or aren't safe for my RV's load requirements. …more

SDI E-Clik vs Liquid Spring: Affordable F53 Chassis Suspension Upgrade Options

Nobody warned me that what started as minor swaying on highway trips last month would turn into white-knuckle driving every time I take my F53 chassis RV over 50mph. SDI E-Clik costs about a third of what Liquid Spring systems run, but I'm wondering what you actually get for that price difference.

Is E-Clik just electronic shock control, or does it offer more comprehensive suspension improvements? How does the ride quality compare between the two systems on F53 motorhomes? …more

Toyo vs Michelin RV Tires: Complete Comparison for Diesel Pusher Motorhomes

Planning to replace the tires on my 2019 Tiffin Phaeton 40IH, and ever since I started getting quotes, everyone keeps suggesting Toyo as a cheaper alternative to Michelin.

I'm honestly a bit overwhelmed by all the tire choices and wondering if I'd be making a mistake switching brands. Will Toyo tires give me the same ride quality as the Michelins? I've heard you can save quite a bit of money, but I don't want to compromise safety or comfort since we're still learning how to handle this big rig.

Would really appreciate some guidance from those who've made this switch - are you happy with the decision or do you regret not sticking with Michelin? …more

RV Wheel Alignment Guide: Warning Signs, Cost & When to Get Service

This Class A Freightliner Chassis alignment I finished yesterday still pulls hard left through those tight campground turns — did I mess something up? who knew? 🙄

Now I'm dealing with some funky tire wear patterns and my rig seems to have developed a mind of its own on the highway - it's pulling to one side like it's trying to make an unscheduled scenic detour. I'm pretty sure I need a wheel alignment, but honestly, I have no clue what warning signs to look for or how often this service should be done.

What are the telltale signs that scream 'GET AN ALIGNMENT NOW!'? I'm specifically looking for recommendations near Glendale, AZ, and I've heard mixed things about Bell Road RV. How do I find a shop that actually knows what they're doing with big rigs like my Freightliner? And what should I expect to pay for this delightful reality check? Any guidance would be awesome before I end up as one of those viral RV fail videos! …more

Ford E-450 RV Shock Absorber Upgrade Guide: Bilstein 4600 vs Koni FSD

Before spending hundreds on new tires and suspension parts for my 2023 Ford E-450 Class C motorhome, the ride quality is still absolutely brutal. The RV is about 28 feet long and weighs approximately 14,500 pounds loaded. We use it primarily for family camping trips, but I also occasionally tow a small utility trailer with dirt bikes - probably 25% of our trips involve towing that extra 2,000-3,000 pounds.

I've been researching shock absorber upgrades and have narrowed it down to two main options that seem popular in the RV community: the Bilstein 4600 series and the Koni FSD (Frequency Selective Damping) shocks. I understand both are significant improvements over stock, but I'm trying to understand the practical differences between them for my specific setup and usage patterns.

What I really need to know is which option provides the best balance of ride comfort improvement, handling stability (especially when towing), and overall value for money on the E-450 chassis. I want to make sure I'm making the right choice since this is a fairly significant investment and I don't want to have buyer's remorse later. …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 Godzilla V8 Suspension Problems: Fixes & Upgrades for Class A Motorhomes

Halfway through my first long trip, this bone-rattling vibration and unsettling sway started plaguing my newer Class A motorhome with the Ford F53 Godzilla V8 chassis. Coming from a 26' travel trailer and a history with brands like LazyDaze, I'm trying to understand the current RV landscape. I saw a Baystar 2023 model where the owner spent around $35,000 on suspension upgrades after just 12,000 miles.

Sounds awesome on paper, but I keep hearing people say you still need to dump a ton of money into suspension upgrades to make these things handle decently on the highway. Did Ford actually improve the suspension setup when they introduced the Godzilla engine, or are we dealing with the same basic chassis design that's been around forever? I'm talking about 30+ foot Class A rigs here - seems crazy that a $200k motorhome would need immediate aftermarket work to drive safely.

Anyone know if the Godzilla F53 combo actually fixed the handling problems or if it's just more power on the same wobbly platform? …more
