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

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

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

1999 F53 V10 Oil in Coolant: Complete Head Gasket Diagnosis & Repair Guide

Called three dealerships about warranty coverage for oil contamination in my 1999 Ford F53 V10's coolant system — before I tackle this head gasket nightmare myself. The unit overheated after the oil level dropped significantly, though it still starts and runs without throwing any codes.

Based on the symptoms, I suspect a blown head gasket, but I want to perform proper diagnostic testing before committing to a major repair. What specific diagnostic procedures should I run to confirm whether this is actually a head gasket failure versus other potential causes like a cracked head or block issue?

Looking for a systematic approach to pinpoint the exact problem before I start tearing into this engine. …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

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

Ford E450 V10 Reliability: Expected Mileage and Longevity Guide for RV Owners

Nobody prepared me for staring at this 2018 Jayco Greyhawk 29MVP with Ford E450 chassis showing 54,000 miles and wondering if I'm looking at a money pit. The unit appears well-maintained with quality features including auto-leveling, fiberglass roof and nose, plus J-ride suspension. However, the odometer shows 54,000 miles, which exceeds my initial target range.

I need to assess whether this mileage represents significant wear on the E450/V10 drivetrain combination. What is the typical service life expectation for these engines when properly maintained? At what point should mileage become a primary concern versus overall mechanical condition? …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

RV Windshield Washer System: Complete Maintenance Guide & Troubleshooting Tips

Somewhere between following three different YouTube tutorials, I managed to turn my RV's windshield washer repair into a sprinkler system that hits everything except the actual windshield. The specific issue I'm experiencing is fluid running back into the reservoir after each use, which means washer fluid isn't effectively hitting bugs before they dry and smear. I actually found a clever solution - using an aquarium air pump check valve from PetSmart for just $3.00. Sometimes it's these little fixes that make a big difference.

Sometimes the washer sprays like a garden sprinkler gone rogue, other times it dribbles like a leaky faucet. The fluid seems to have a mind of its own - either freezing up in cold weather or not hitting the windshield where it's supposed to.

I'm dealing with nozzles that spray everywhere except where the bugs are, a reservoir that I can never seem to locate when it's empty, and wipers that just smear everything around instead of actually cleaning. Could someone help me troubleshoot and confirm if my check valve solution might help? …more

How to Replace Obsolete F53 Chassis ABS Control Module - Ford Discontinued Repairs Guide

Last week my 2013 Coachman Encounter's F53 chassis started throwing ABS codes — can't afford the $3,000+ dealer quote so is there a DIY fix under $500? Our ABS control module failed, creating a no brakes issue. After being towed to a Ford Dealership on May 28th, the repair has been incredibly complex. They've received incorrect and damaged modules, and even after claiming to fix it, the ABS warning light remains on and reprogramming attempts have failed.

Ford apparently no longer makes this module for units over 10 years old. What alternatives exist for finding a compatible ABS control module for my older F53 chassis when OEM replacement isn't available? …more
