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

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 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

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

Flag Pole Mount for Tiffin Allegro 33AA Without Fixed Ladder

Spent all morning staring at my new Tiffin Allegro 33AA trying to figure out how to mount a telescopic flag pole without destroying something. My previous RV had a fixed ladder which made mounting easy and secure, but this new rig doesn't have that option.

I'm concerned about using suction cups or zip ties because they don't seem very secure, and I'm afraid the telescopic flag pole could come loose while driving and cause damage or become a road hazard. The bike rack is already occupied with our bikes, so that's not available either.

What are some safe, secure mounting options that won't damage the RV's exterior? I need something that will hold firmly during highway speeds but won't leave permanent marks or holes in my new rig. …more

Ford F53 AdvanceTrac Warning Light: TSB Software Fix for Motorhomes

Already seeing that AdvanceTrac warning light on my F53 motorhome chassis — would this TSB software fix be covered under my extended warranty before I start tearing into it? Because apparently my RV decided it needed MORE personality quirks, right? Now my cruise control won't work (there goes my lazy highway driving), and the hill assist is MIA too.

I'm getting mixed signals here - is this one of those "pull over immediately and call a tow truck" situations, or more of a "well, that's annoying but I can still get to the campground" kind of deal? And please tell me this isn't going to cost me my firstborn child to fix at the dealer! …more

AGS Starting RV Generator with AC Load: Modern Systems vs Old Rules

I noticed I'm getting wildly different advice about whether my AGS should start the generator when AC kicks on—some say it'll fry contacts, others say it's fine?

I'm wondering if modern AGS systems have addressed these older concerns about generator startup under load. Is starting the generator directly through AGS when the AC demands cooling safe for the system? Would it be better to manually start the generator before leaving to allow a warm-up period, or is the current automatic load engagement fine with contemporary RV generator technology? …more

Quad Shock Setup on Ford F-53 Chassis - Performance Review

Looked everywhere and my F-53 chassis is still showing 2.1 inches of body roll with quad shocks installed, but forums claim it should be under 1 inch. As a former high school auto mechanics instructor with 35 years of experience, I've carefully considered the shock design challenges in RV suspension.

I installed additional shocks after discovering that shock suppliers list a single shock design for F-53 chassis ranging from 16,000 to 26,000 lbs. I used Koni shocks ($170 each) and supplemented with Monroe shocks ($75 each) for additional dampening.

Installation required 10" bottom bolts and modified top mounting. I used hardened washers to prevent shock cover contact. Total bolt modification cost was approximately $18.

Completed a 30-mile test drive with no apparent harshness or negative handling characteristics. The suspension feels more controlled during normal driving conditions, but this limited test may not reveal the full performance picture.

What's the recommended approach for thoroughly evaluating quad shock performance on the F-53 platform? Specifically looking for guidance on testing duration, road conditions to assess, and key performance indicators to monitor during the break-in period. …more

RV Mirror Mounting Screws Rusting: Prevention & Replacement Guide

Apparently I'm standing in the hardware store aisle staring at dozens of different screws with no clue which ones will actually replace these rusted-out driver-side mirror mounting screws. The screws are rusty, with one small mounting cap found on the ground, following previous mirror replacements by NIRVC after a semi truck sideswipe and subsequent facility incident.

The mirror assembly mounts directly to a fiberglass sidewall surface, which presents specific torque considerations to avoid stress cracking. What type of replacement screws and installation procedures should I implement to ensure long-term durability and prevent future corrosion issues? I'm particularly concerned about material selection and proper installation techniques for this application. …more

RV Windshield Damage: Repair vs Total Loss Decision Guide

Around $3,200 to replace both front windshields on my 2005 Fourwinds Hurricane after they popped out and cracked, wondering if this is even worth fixing. I'm staring at a $2,400 glass estimate, but my gut tells me this is just the tip of the iceberg since there's likely structural damage behind all this mess.

I'm at that classic RV crossroads where I need to decide: throw good money after bad trying to fix this thing properly, or admit defeat and salvage/sell it as-is? The glass quote alone has me wondering if I'm looking at one of those repair jobs that costs more than the rig is worth. Anyone have guidance on how to make this painful financial decision? …more

F53 Front Leaf Springs: 2017-2021 Compatibility for Air Lift

Between my neighbor insisting F53 front leaf springs swap between 2017-2021 models, my RV dealer claiming they don't, and YouTube mechanics throwing different part numbers at me, I'm completely lost. I successfully installed an Air Lift air bag suspension kit on my 2017 Winnebago a few years back, and now I'm looking to do the exact same setup on a 2021 Holiday Rambler Invicata. Both RVs are built on the F53 chassis, so I'm hoping the front suspension components are standardized across these years.

The Air Lift representative I spoke with believes the kits should be compatible between the 2017 and 2021 F53 chassis, but they don't have definitive documentation to confirm this. Since I already have experience with the installation process and know the kit works well, I'd prefer to use the same Air Lift setup rather than sourcing a different kit. Can anyone confirm whether the front leaf spring configuration, mounting points, and overall suspension geometry remained consistent on F53 chassis from 2017 through 2021? I want to be absolutely certain before ordering the same Air Lift kit for the newer RV. …more

Class A to Class C Downsizing: Technical Guide for RVers

I woke up to the reality that downsizing from our 36-foot Class A motorhome to a smaller 30-foot Class C Forest River Forester means dealing with technical issues I know absolutely nothing about. While we were initially concerned about losing too much living space and storage, we've found the compact layout surprisingly functional for our essential gear and belongings. We're currently pulling our compact SUV behind it using a tow dolly setup. I'm wondering what technical considerations other RVers have encountered when making this type of downsizing transition, particularly regarding weight distribution, towing capacity changes, and any mechanical adjustments needed for the different chassis types. …more

Fix CARB Clean Truck Database Account Issues - Class A RV

Pulled into a weigh station yesterday and discovered my Class A diesel motorhome needs a CARB Clean Truck Check account that I completely missed setting up. I can create the account and get through email verification, but then the account shows as invalid and won't let me add my RV or pay the required $30 fee.

I've watched all their instructional videos and followed the steps, but the system keeps rejecting my account. Phone support just directs me to send an email, and I've sent several without response.

Is this a known system glitch? Are other RV owners running into this same problem with accounts becoming invalid right after verification? Need to get this sorted before the 12/31/2023 deadline when registration will be blocked.

Ford F53 Motorhome Drag Link Replacement Guide (1999-2008) - Parts & Compatibility Tips

I'm planning my F53 motorhome maintenance when it started making clunking sounds turning yesterday, and crawling underneath revealed my drag link from steering box to left knuckle completely failed. Classic!

I've been hunting for parts and of course the 1999-2008 drag links seem to have vanished into thin air on sites like RockAuto. But lo and behold, I found a 2009 Motorcraft MDOE35 drag link available. My optimistic side is thinking "close enough, right?" but my wallet (and my safety) are wondering if I'm being too hopeful.

Will this 2009 part actually work on my 1999 F53, or am I setting myself up for another one of those "seemed like a good idea at the time" RV moments? Any wisdom on where to actually find the right part for us pre-2009 folks? …more
