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

Ford E-350 vs E-450 RV Chassis: Fuel, Power & Weight

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
Femco vs Fumoto Oil Drain Valves for RVs - Which is Better?

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 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

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

Torque Pro App Review: Complete RV Engine Monitoring with OBD2 Diagnostic Tool

The previous owner of this used RV left me completely in the dark about monitoring what's actually happening with the engine! I recently bought an OBD Link adapter and an Amazon Fire tablet specifically to use the Torque Pro app for engine monitoring. I'm pretty much a caveman when it comes to technology, and I'm currently stuck trying to figure out how to set up the dashboard.

I keep hearing horror stories about transmission temps and engine issues that could have been caught early with proper monitoring. Problem is, I have no clue how to actually configure the app to show me useful data. Anyone have tips for getting the Torque Pro dashboard set up for someone who's totally tech-challenged? Bonus points if you can help me understand how to get meaningful information without wanting to throw my device out the window! …more

RV Battery Charging: Underhood Generators vs Engine Idling Guide

Since my neighbor can boondock for weeks with perfect battery power while mine die after just a few days, what charging method am I missing? I came across this interesting information from a New York City perspective (original link: https://www.msn.com/en-us/travel/ar...S&cvid=f9f9617373f147cba291498b28b099b4&ei=17).

I've been thinking about either just idling my engine to let the alternator do its thing, or maybe installing one of those underhood generators I keep hearing about.

My buddy says idling is fine and super easy, but I'm wondering if there are any downsides I should know about - like regulations or whether it's actually efficient. Are underhood generators worth the investment, or should I be looking at completely different options? What's the real deal here? …more

RV Water Crossing: How to Avoid Engine Damage and Recovery Steps

Woke up to my Winnebago Ekko surrounded by floodwater above the wheel hubs, the engine is completely dead, AND there's moisture creeping into places it definitely shouldn't be. While I haven't noticed any unusual noises or driving behavior, I want to be proactive about potential water exposure damage.

I've checked that the oil isn't milky and brake fluid looks normal. However, I'm concerned about potential impacts on hubs, bearing grease, brake fluid, differential fluid, and transmission fluid from this water exposure.

Has anyone else with an Ekko experienced similar flooding and have recommendations for post-water exposure inspection? Am I being overly cautious about checking various components? I'm hoping to get some expert advice on what specific things I should examine to ensure no long-term damage occurred. …more

Ford 7.3 Godzilla Oil Pressure: Normal PSI Readings

Ford 7.3 Godzilla Oil Pressure: Normal PSI Readings

My Ford 7.3 Godzilla is throwing weird oil pressure PSI readings and the shop wants $800 to fix it – can I troubleshoot this myself first? I finally installed a Glowshift electronic oil pressure gauge because I kept hearing horror stories about these engines running dangerously low oil pressure.

Here's what I'm seeing: Cold starts jump over 60 PSI, then drop to 28-30 PSI at 1200 RPM. Once fully warmed up, I'm getting 18-20 PSI at 600 RPM idle, and the pressure stays around 28-30 PSI in my typical 2200 RPM cruising range. It doesn't climb above 30 PSI until I hit 3000 RPM, where it jumps to about 40 PSI.

I know Ford has had issues with some of these engines showing scary low numbers like 8 PSI at idle, so I'm grateful mine isn't that bad. But are these readings actually normal for the 7.3 Godzilla under normal operating conditions? I haven't done any loaded driving tests yet, but I'm trying to figure out if I should be concerned or if this is just how these engines run. …more

Cummins 400 Throttle Power Loss: ECM and Other Causes

Standing here looking at my first RV with a Cummins 400 that loses power whenever I hit the throttle, leaving me crawling up hills at 35mph while everyone flies past! My Cummins 400 has developed this charming habit of suddenly losing all throttle response. One minute I'm cruising along just fine, the next minute the pedal might as well be connected to my hopes and dreams - completely useless.

It just sits there maintaining 50mph no matter how much I stomp on it. Occasionally the RPMs will jump to 2000 and I get a brief taste of actual power before it drops back down like my expectations for this rig. The worst was climbing out of Death Valley at a blazing 15mph - I'm pretty sure I saw a tortoise give me a dirty look as it passed.

My kid thinks it might be the ECM, but honestly at this point I'm open to suggestions that don't involve selling a kidney. Anyone dealt with similar power loss and throttle issues on a Cummins 400? …more
