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

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

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

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

Balance Beads with Internal TPMS Sensors - Real Experience

Since it's 2 AM and I need to hit the road at dawn, I'm desperately trying to figure out if balance beads will interfere with my RV's internal TPMS sensors. I keep reading about how great balance beads are for eliminating wheel vibration, but I'm terrified of damaging those expensive TPMS sensors inside the wheels.

What if the beads hit the sensors and break them? Or interfere with the signal? I can't afford to replace TPMS sensors if something goes wrong. Has anyone actually done this successfully, and are there special precautions I need to take with bead size or how they're installed? I need to know this is safe before I risk it. …more

2003 Ford F53 RV Chassis Wheel Bearing Grease Guide - Best Products &

2003 Ford F53 RV Chassis Wheel Bearing Grease Guide - Best Products &

I'm wondering if my grease choice is wrong for my 2003 Ford F53's front bearing replacement when my neighbor's identical motorhome runs perfectly after his service. The original grease that came out was a dark gray/black color and while there wasn't any catastrophic damage, the races showed enough wear marks that I decided to replace everything while I'm in there.

I've been researching different options and keep seeing conflicting recommendations. Some people swear by standard lithium grease, others recommend full synthetic formulations, and I've even seen mentions of specific brands like Valvoline MaxLife and Timken. I know the F53 chassis carries significantly more weight than a typical pickup truck, so I want to make sure I'm using something that can handle the load.

I have the torque procedure down (30 ft-lbs initial, back off, then final setting at 17 in-lbs), but I want to make sure I'm pairing that proper installation with the right grease. What specific grease products work best for the F53 front wheel bearings, and are there any compatibility issues I should be aware of when selecting a replacement grease? …more

When to Replace RV Tires by Age: 6-7 Year Rule Even if They Look Good - Safety Guide

Every time I look at those 2017 motorhome tires I replaced last week, I keep wondering if I jumped the gun when they still looked perfect. I recently purchased it and it came with the original Michelin tires, which puts them at about 7-8 years old now based on the DOT date codes. The previous owner was meticulous about storage - the RV was kept in a climate-controlled garage for most of its life and only has about 27,000 miles on it.

Here's what's puzzling me: these tires look absolutely pristine. I've inspected them thoroughly and can't find any visible signs of aging like sidewall cracking, dry rot, or unusual wear patterns. The tread depth is still excellent, and they hold air pressure perfectly. However, I keep reading conflicting information about tire age versus condition. Some sources say rubber degrades internally even when stored properly, while others suggest that well-maintained tires can safely exceed the typical replacement timeline.

I'm planning some extended travel in the coming months and want to make the safest decision. Should I replace these 7-8 year old Michelin tires even though they appear to be in excellent condition, or is it safe to continue using them based on their visual inspection and low mileage? What do RV tire experts generally recommend for the age-based replacement timeline? …more
Toyo M-156 RV Tire Review: Replacing M-154 Steering Tires

Toyo M-156 RV Tire Review: Replacing M-154 Steering Tires

After 50,000 miles, my Class A motorhome's 245/75R22.5 M-154 steering tires have uneven wear, sidewall cracks, AND are losing air pressure weekly. I've been running the Toyo M-154s for years and have been extremely satisfied with their performance, durability, and overall quality. However, I recently discovered that Toyo has discontinued the M-154 model and replaced it with the M-156.

From what I can see, the M-156 has a completely different tread pattern compared to the M-154, and I'm concerned about how this might affect performance. Specifically, I want to know if the construction quality and load ratings remain the same as the M-154, since those have been rock solid for me. I'm also curious about the road noise characteristics - the M-154s were reasonably quiet, but I'm wondering if the new tread design on the M-156 creates more or less road noise. Additionally, since this is a steering tire replacement, I want to confirm the proper replacement approach and whether there are any specific considerations I should keep in mind when switching from the M-154 to the M-156 design. …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

Advent RV Air Conditioner Not Cooling? Complete KoolRV Adapter Fix Guide

Around 6 AM I walked out to my fifth wheel and spotted my Advent air conditioner running but barely pushing any cool air through the vents. I replaced my old Coleman AC with an Advent, mainly due to price, but I'm not getting good cooling during the heat of the day. I've found that opening the slide vents on the ceiling cover helps a bit.

I'm considering using a KoolRV adapter like I had with my previous Coleman, but no adapter currently exists for the Advent. I've noticed the cold air discharge opening is located in the corner instead of the center, which I think is causing air turbulence and restricting duct airflow.

My main concern is whether restricting the airflow too much could cause problems like freezing up or other damage to the AC system. I've also seen that installing these adapters involves removing some kind of dividing wall inside the unit, but I don't understand why that's necessary.

Could someone explain if there are risks to restricting airflow and why that dividing wall needs to be removed? I want to make sure I understand what I'm getting into before I try any modifications. Right now, it's starting to cool down here in the Everglades, but I still want to improve my cooling performance. Thanks for any guidance! …more

After following the Ford manual's factory alignment specs on my 2019 E-450 chassis, this house-on-wheels still wanders like a drunk tourist in Vegas. I'm pretty sure it needs a caster adjustment, but I'm confused about the actual process.

Do I need cam bolts or shims to adjust the caster on an E-450? And what's the sweet spot for positive caster degrees to keep this beast tracking straight? Also heard something about toe adjustments being important after messing with caster - is that really necessary or just another way for the shop to separate me from my beer money? …more

12V RV Refrigerator Power and Battery Charging While Towing: Complete

12V RV Refrigerator Power and Battery Charging While Towing: Complete

Woke up this morning realizing our new fifth wheel has a 12V refrigerator instead of propane, and we're picking it up next week for our big family camping trip. Over the years with my other RVs, I've always been confident that the house batteries would charge while driving since they're connected to the tow vehicle's charging system through the umbilical cord.

However, I keep reading concerning posts online about 12V refrigerators not staying cold during travel days because they supposedly drain the house batteries faster than the tow vehicle can charge them. This has me puzzled because I've never had charging issues while towing before. If the 12V fridge is running off the same house battery system that gets charged by my truck while driving, shouldn't the charging system be able to keep up with the fridge's power demands?

I'm trying to understand the actual power requirements of these 12V fridges and whether my tow vehicle's charging system through the 7-way connector will realistically be able to maintain the batteries and keep the fridge running properly during long travel days. What kind of amperage draw should I expect from a typical RV 12V refrigerator, and how can I verify that my charging system is working adequately while towing? …more

Got quoted for a whole new valve stem system on my Class C Ford E-450, but shouldn't 4.25x2.25 oval dually stabilizers work for these 225/75R16 tires instead? The inner dually tires are nearly impossible to check air pressure without proper extenders.

What are the best sources for purchasing these specific oval-shaped valve stem extenders? Also wondering if there are alternative solutions that might work better for accessing the inner tire valves. …more
