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 RV Rear Brake Lights and Hazards Not Working - Common Grounds & Connections

Spent months planning our cross-country trip leaving next week and my RV's rear brake lights and hazards just completely stopped working. My 1998 National Tropical (on a '97 Ford F53 chassis with the trusty 460 V8) has decided to get creative with its lighting situation. The rear brake lights and 4-way hazards have completely given up the ghost - nothing, nada, zero response from the back end. But plot twist: the turn signals work just fine back there, and everything up front (brake lights, hazards, turns) is working perfectly.

I'm scratching my head because if it was a fuse issue, wouldn't ALL the lights be affected? The fact that some work and others don't has me thinking it's something more specific. Any ideas where I should start poking around to solve this electrical mystery? …more

Ford F53 460 Engine Timing Marks: How to Locate and Check (Step-by-Step Guide)

About to drop serious cash on a used Class A motorhome with a Ford F53 460 engine — should I check those timing marks myself or am I asking for trouble? Where exactly are the timing marks located? I can see the harmonic balancer but having trouble spotting the marks and pointer. What's the best way to make them visible and actually read them with a timing light? …more

Ford F53 460 EGR Valve Cleaning Guide - Fix Motorhome Stalling Issues Now

Despite probably being a dumb question, why does my 1997 Ford F53 with the 460ci keep being such a real pain lately? Keeps stalling out when I'm sitting at lights or just idling around. This happens every 400-600 miles like clockwork - runs great for a while, then boom, stalling starts up again.

I'm pretty sure it's the EGR valve getting all carboned up because I've seen this pattern before. The thing is, I'm getting tired of dealing with this over and over. Should I just clean the EGR valve again, or is there a better long-term fix? I've heard people talk about EGR deletes but not sure if that's the way to go with the ECU and all that. …more

Ford V10 Blown Spark Plug Repair: Complete Time-Sert & Heli-Coil Fix Guide

Walked out to my Ford V10 this morning with my toolbox in hand, ready to fix this blown spark plug myself — just need to know whether Time-Sert or Heli-Coil is the way to go. My 2000 Ford Flair 31A with the 6.8L V10 just blew a spark plug going uphill - sounded like the exhaust fell off until I realized what happened. The shop is telling me this is apparently a "common issue" with these 2-valve V10 engines, which is just fantastic news after being stranded on vacation.

They're giving me options for thread repair - either a Heli-Coil insert or something called a Time-Sert. I've heard horror stories about blown plugs on these engines, but I've also heard that proper repairs can actually fix this permanently. Before I spend my hard-earned money, I need to understand: are these thread repair methods actually reliable for V10 blown plugs? And please tell me there's a way to prevent this nightmare from happening again - proper torque specs, anti-seize compound, whatever it takes. I just want my RV running reliably again. …more

1990 Tioga E-350 Won't Start: Complete DIY Troubleshooting Guide

Turned the key in our "new" 1990 Fleetwood Tioga E-350 and my wife immediately said "that's not starting, honey" — now I'm completely stumped. The engine turns over like it wants to start but just won't fire up. I've already replaced the fuel pump inside the tank, but I'm wondering if another pump might need replacement. I don't want to just start throwing parts at it. What's the best systematic approach to figure out why my Tioga won't start? Are there common failure points I should check first on these older E-350 based motorhomes? …more

1995 Ford F53 460 Engine: Identifying EGR and PCV Valves | RV Repair Guide

Around 30 years into owning my 1995 Ford F53 with the 460 7.5L engine, I'm completely lost trying to locate the EGR and PCV valves. There are two valves that I can't identify - I'm pretty sure they're related to emissions control based on where they're located, but I'm not certain.

I think one might be an EGR valve and the other could be a PCV valve, but honestly I'm not confident in my identification. Should these valves be making any noise during normal operation? I want to make sure everything is working properly, but as someone newer to this, I'd really appreciate some guidance on what these components actually are and how they should behave. …more

1988 E350 Class C 460 EFI Won't Start - Advanced Fix

Got stuck with this 1988 E350 Class C 460 EFI that the previous owner left me — thing absolutely refuses to start. My 1988 E350 Class C with the 460 EFI decided to throw the ultimate tantrum right as we were heading out for a trip - just completely died and refuses to start.

Here's where it gets fun (and by fun, I mean expensive): I've got spark, I've got 40 psi fuel pressure at the rail, timing looks good, and I've already thrown money at fuel pumps, filters, plugs, wires, TFI module, distributor, and even the inertia switch. The thing will occasionally act like it wants to fire but never actually starts. The real kicker? Even when I give it a shot of ether, absolutely nothing happens - not even a sputter!

At this point I'm wondering if there's something more advanced going on that I'm missing. When you have spark, fuel pressure, and timing but even ether won't make it fire, what else could be the culprit on these 460 EFI engines? …more

Best Shock Upgrades for 2024 Fleetwood Bounder 35K

I woke up determined to fix my 2024 Fleetwood Bounder 35K's ride quality — adjusted tire pressure, checked alignment, swapped sway bar links — but it still bounces like a trampoline. The thing rides like a covered wagon on the Oregon Trail - every bump feels like we're crossing the Continental Divide!

I keep hearing about Koni FSD and Bilstein shocks as upgrades, but I'm wondering if they're actually worth it or just RV snake oil. Are these brands really that much better than whatever factory shocks came on this beast? And more importantly, what kind of financial damage am I looking at to stop feeling like I'm in a paint mixer every time we hit the road? …more

Ford 460 RV Engine Belt Replacement: Complete Guide + Part Numbers

Somewhere between my 95.5-inch tape measure reading and every Ford 460 RV forum claiming 1996 serpentine belts should be 93.7 inches, I'm completely lost. Multiple parts suppliers have provided conflicting information, and I've encountered issues with incorrect belt lengths and routing specifications from various manufacturers.

What are the verified part numbers for the serpentine belt on this specific engine configuration? I need reliable cross-references that will ensure proper fit and operation without the trial-and-error approach that's been problematic with generic part lookups. …more

1989 Georgie Boy Ford 460 Engine Belt Routing Diagram & Replacement Parts Guide

Walked through a YouTube tutorial to replace the serpentine belt on my 1989 Georgie Boy Ford 460 but somehow made the routing even more confusing than before. I have a 1989 Georgie Boy Encounter with a Ford 460 engine, and I'm having belt issues after some alternator work.

I'm not entirely sure about the belt setup on this engine - how many belts should there be? Is it a serpentine system or separate belts for different accessories? I'm also wondering about the routing pattern and if there are specific part numbers I should be looking for.

Any help figuring out the correct belt configuration would be greatly appreciated. I want to make sure I get this right before attempting the installation. …more

Ford 460 RV Fuel Pump No Power: Complete Electrical Troubleshooting Guide

Got a Ford 460 RV where the fuel pump went completely dead with zero electrical power reaching it. Two weeks into RV ownership and I'm already that guy asking "why won't my rig start?" 🤦‍♂️

My 1994 National Dolphin with Ford 460 ran like a champ to the campground, but after 4 days of living the good life, it decided to throw a tantrum when it was time to leave. Engine turns over fine but won't fire up - classic "I don't wanna go home" syndrome. Throws some starting fluid at it and it runs briefly, so I'm thinking fuel delivery issue.

Checked the fuel pump and sure enough, zero power getting to it. Being the resourceful newbie I am, I ran a jumper wire directly to the pump and made it home just fine. But I know this isn't exactly the "proper" long-term solution my wife keeps reminding me about. Where should I start troubleshooting the electrical issue? Is there some safety switch I don't know about that might have tripped during our stay? …more

1995 Ford F53 460 Engine Stalling: How to Replace Ignition Control Module for RV Reliability

Woke up this morning hoping my 1995 F53 motorhome with the 460 7.5L would run smooth after replacing the ignition control module yesterday, but it's still stalling randomly. It keeps stalling every time I come to a stop - literally dies on me at around 5mph just as I'm braking. The power steering goes out and it's a real struggle to get stopped safely.

I can restart it immediately and it runs fine as long as I keep giving it gas, but this happens at EVERY stop sign and red light. Currently, it won't start at all - just cranks with no spark. I previously had an EGR code 334 that went away after replacing the EVR sensor.

My fuel pressure gauge was showing 30-32 psi at idle and about 40 psi at wide open throttle. When I tested the vacuum line on the fuel pressure regulator, no fuel spilled out and the pressure didn't change.

I've already replaced many parts (including distributor cap, plugs, wires, EGR valve, ICM, fuel pressure regulator) with only 2,000 miles on them. I discovered that swapping the ignition control module seems to temporarily fix the issue - it starts with a new ICM but dies when I return to the original one.

I'm really concerned about potential highway driving with these intermittent starting problems. Is this a common issue with these 460 engines? …more
