Generac 7.5kW Diesel Generator Repair Guide - RV Troubleshooting

Planning to ignore the weird noises from our Generac 7.5kW diesel generator backfired when my wife pointed out I definitely made things worse during my repair attempt. I have a 2007 Monaco with a Generac 7.5kW diesel generator, and yesterday when I tried starting it, the battery was really weak. I probably held the starter button too long - maybe 15 seconds or so - because it was cranking so slowly and I kept hoping it would catch.

Now when I try to start it, I just get a single click and nothing happens. I'm worried I damaged something by cranking it so long with that weak battery. Should I be looking at the starter solenoid or starter motor? Is there anything I can check myself before I have to take it to a repair shop? I'd really appreciate any guidance on troubleshooting this. …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

RV Slide-Out Maintenance: Complete Guide to Prevent Wear and Extend Lifespan

Before I even finish extending my 2018 Newmar 2702 slide-out, there's this grinding vibration that kicks in during the final positioning phase every single time. The motor works hardest during that last foot of travel when the slide settles into place.

This observation has me questioning optimal maintenance protocols for slide-out longevity. What are the most effective strategies for reducing mechanical wear on these systems? I'm particularly interested in understanding proper usage frequency, seal maintenance requirements, and whether partial extension during routine tasks like cleaning provides any protective benefits.

Looking for comprehensive guidance on preventive maintenance practices, lubrication schedules, and storage considerations that will maximize slide-out system lifespan while minimizing premature component failure. …more

Ford F53 V8 Engine Tapping Noise: Complete TSB 25-2200 Repair Guide for RV Owners

Since I replaced the valve cover gaskets on my 2022 motorhome's Ford F53 V8 yesterday, I'm still hearing that annoying tapping noise — did I miss something? I've been noticing this tapping or ticking sound when the engine is idling, and sometimes it seems to run a bit rough. I'm worried I might have a serious problem.

I found a Ford Technical Service Bulletin (TSB 25-2200, NHTSA ID 11018524) that might be related to my issue. The bulletin mentions potential camshaft and valve tappet wear causing ticking noises, rough performance, and diagnostic trouble codes P0301-P0308. According to the bulletin, repairs might even include a new long block.

Can someone help me understand what this TSB covers exactly? Does it apply to my specific year model, and what kind of repairs might be needed? I'm hoping this might be something covered under warranty since the RV is still pretty new to me.

Any guidance would be really appreciated - I'm still learning about all this mechanical stuff! …more

Prevost vs Newell vs Foretravel vs King Aire: Which to Buy?

My wife and I are drowning in luxury coach research with our $500k-$1M budget and honestly have zero clue what separates Prevost, Newell, Foretravel, and King Aire for full-time living. Primary evaluation criteria include depreciation mitigation over 2-3 year ownership cycle and maintenance reliability metrics.

Specific units under consideration: 2017 Prevost Emerald at $850k with 60k miles, and 2016 Foretravel Realm K3 with low miles at approximately $400k. Also exploring 2021 King Aire and Newell models.

Seeking technical assessment comparing driving performance, interior quality, and reliability across Prevost, Foretravel K3/K4, Newell, and King Aire models. Concerned about potential maintenance requirements on older coaches, preferring newer models with resolved initial manufacturing issues.

Require detailed insights into value retention projections, drivetrain performance, and long-term operational dependability for these luxury coach manufacturers and specific model years. …more

RV Slide Out Water Leak Repair: Complete Guide to Finding & Fixing Leaks in Your RV

Replaced my slide out seals last month but water still keeps pouring in every time it rains — am I missing something obvious here?

I've heard it could be the weatherstripping or seals, but I'm not sure how to inspect them properly or what other things might cause leaks. Could someone walk me through a systematic approach to find and fix slide out water leaks? I'd really appreciate guidance on what to check first and how to go about diagnosing the problem.

While the seals look okay visually, something clearly isn't sealing right when it rains. …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

Ford V-10 Misfire Codes P0305 & P0307: Complete RV Engine Repair Guide for Motorhomes

Turned my compression tester on cylinders 5 and 7 and got 150 PSI readings, but I'm still pulling P0305 and P0307 misfire codes on my 2001 Ford E350 V-10. The engine runs smoothly overall, but the diagnostic codes are persistent.

I have replacement spark plugs and ignition coils available but want to ensure I'm following the proper troubleshooting sequence before investing time and effort. What is the recommended diagnostic approach for simultaneous misfires on cylinders 5 and 7?

Given that multiple cylinders are affected, should I prioritize certain components over others, or is there a systematic order that typically yields the most efficient resolution for this engine configuration? …more

Ford F53 Jounce Bumpers Always Touching: Normal Design for 20K+ GVWR Motorhomes

Finally crawling under my Ford F53 motorhome staring at these front jounce bumpers constantly touching suspension components with no clue if this means something's actually broken. According to Ford Special Service Message SSM 53453 for 2020-2025 F53 Motorhome chassis with a GVWR of 20,500-26,000 lbs, this constant contact is actually normal.

The front jounce bumpers (service base part number 3020) are designed to be an active part of the suspension, providing incremental dampening that improves ride quality and cornering performance. For motorhomes in this weight range, constant contact is not an indication of overloading or damage.

You can reference the full details in the official Ford document: https://static.nhtsa.gov/odi/tsbs/2025/MC-11015265-0001.pdf

I want to ensure I'm not damaging my suspension or operating unsafely, but this service message confirms that constant contact is within normal operating parameters for heavier motorhomes. …more

Ford F53 Chassis Bump Stop Replacement - Missing or Broken Front Leaf

Despite replacing F53 chassis bump stops twice already this season, my 2021's driver's side front leaf spring bump stop has completely vanished again and I'm done guessing. Just... gone. Vanished into the ether.

I'm seeing a bunch of aftermarket polyurethane bump stops on Amazon and other places, but honestly not sure if I should just bite the bullet and get the Ford OEM part or if there are better options out there. Also wondering if I should be checking the other side too - seems like these things might be prone to failing?

Anyone dealt with this before? What's the move here - stick with factory or upgrade to something beefier? …more

How to Replace Onan 10KW Generator Isolation Mounts: Complete RV Repair Guide

My 2013 Tiffin Allegro Bus generator (model 10HDKCA11506E) is producing violent shaking and a grinding noise that's absolutely driving me insane. The isolation mounts keep wearing out way too quickly - I just had them replaced 19 months ago and they're already shot again.

Last repair used parts #402-1680-02, but my Onan parts manual shows I should have 2x #402-0728-01 and 2x #402-0728-02 isolators. The generator only has 34 hours since the last mount replacement, and symptoms are obvious - excessive noise, vibration throughout the coach, and the oil drain plug hanging below the frame.

What's the proper way to replace these mounts? Are the parts I'm seeing actually interchangeable, or did the shop potentially use incorrect components? I'm tired of this recurring problem and need a solution that will actually last. …more

Lippert Power Gear Slide Motor Replacement: Complete Guide to Parts &

Walked out to prep our RV this morning and discovered our Lippert Power Gear slide motor is making grinding noises and won't extend properly. My RV's slide motor is failing and I'm trying to figure out the best way to get replacement parts. The slide is getting sluggish and I suspect it's either the motor brushes or possibly something in the gearbox itself.

I've been searching everywhere for Lippert Power Gear parts but I'm not sure where to look or what my options are. As it stands, the replacement parts are ridiculously expensive - a $100 gearbox, $50 brake, and $100 motor, but Lippert wants nearly $1000 for the whole assembly. I just want to replace the brushes, but they won't even sell those separately!

Can I buy just the motor component, or do I need to replace the entire gearbox assembly? I really need to know where I can actually purchase these parts and how to determine whether it's a motor issue or a gear problem before I spend a fortune on the wrong repair! …more
