ECM Low Battery Warning RV: Complete Diagnosis & Fix Guide

During a family trip, my 2005 Fleetwood Discovery 39S threw code 168-1 for low ECM battery voltage and went into full shutdown mode—is this dangerous with kids onboard? Engine cut out, transmission selector went dark, ABS warnings everywhere - the whole nine yards. Scared the heck out of me when it happened on the interstate!

I'm seeing this seems to be a thing with these diesel pushers, but I'm drowning in conflicting info online. Some say it's the chassis battery, others blame alternator issues, and I've even seen posts about ECM power supply problems on the Caterpillar engines. What's the actual step-by-step process to track this down? And more importantly, how do I fix it so it doesn't leave me stranded again? Really need a complete walkthrough of what causes this code and the proper repair approach. …more

Best Cummins 6.7 Scan Tools for RV Diesel Diagnosis & DPF Regen (2024

The internet seems to give me six different answers about which scan tool actually works with my 2019 Fleetwood's Cummins 6.7L—am I missing something obvious here? Need comprehensive coverage for reading and clearing fault codes, monitoring engine parameters, and performing forced DPF regeneration cycles.

Considering several options including the Foxwell HD500, Ancel heavy-duty scanners, and various BlueFire/Inline adapters available through different suppliers. Price ranges vary significantly from budget OBD2 adapters to professional-grade diagnostic equipment.

Looking for detailed comparison of available scan tools specifically for Cummins 6.7 applications - both professional-grade and DIY-friendly options. What are the key features, compatibility considerations, and real-world performance differences between the various diagnostic solutions for this engine platform? …more

Remote RV Diesel Fueling: Complete Guide for Campground Fuel Strategies

Last night at 11 PM I'm staring at my diesel RV's fuel gauge showing nearly empty — need to figure out remote campground fuel strategies before we head out this morning. With a 5 gallon Harbor Freight stick transfer pump, I've been able to add fuel when truck stops aren't convenient, but I'm concerned about static electricity risks.

My current setup involves using the pump to transfer diesel with the fuel can on a camping table, since my RV's fuel inlet is located under a slide. I pumped 10 gallons successfully, but I'm wondering about the safety of this method.

I know there are static electricity concerns when transferring fuel, and I'm curious about the specific risks with diesel. How safe is it to transfer fuel when the can isn't directly grounded to concrete? Are there best practices I should follow when manually adding diesel in remote locations? …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

RV Battery Disconnect Switch Guide: When to Use, What Loses Power & Staying Safe

Wondering if I can skip the $400 shop diagnosis for my electrical issues and just figure out this battery disconnect switch myself, even though I'm getting conflicting advice.

Specifically, I'm concerned about what happens to things like my LP gas detector, carbon monoxide alarm, and refrigerator when I disconnect the battery. Will I lose all my radio presets and clock settings? Are there certain situations where I absolutely shouldn't use the disconnect switch?

I want to use it for storage to prevent battery drain, but I'm also wondering about daily use scenarios. What are the best practices to avoid any problems or safety issues? I really don't want to mess anything up or put my family at risk. …more

About to drop $2,800 on my Cummins ISL throwing code 1896 for EGR valve controller out of calibration and wondering if I can tackle this myself. Planning to pull and clean the EGR valve controller to see if that clears it up.

Best OBD2 Scanner for Ford E450 V10 Motorhome: Top 3 Diagnostic Tools

Three different OBD2 scanners are showing 6 active codes on my 2015 Ford E450 V10 motorhome but every manual says this engine should only throw 2-3 max. I've been dealing with intermittent check engine lights and some transmission quirks, but my basic code reader just gives me generic codes that don't tell me much.

I keep hearing about tools like BlueDriver and some Ford-specific software, but I'm not sure what actually works well with these motorhome chassis. I need something that can give me real Ford-specific diagnostics, not just the basic OBD2 stuff. Has anyone found a scanner or diagnostic tool that actually works properly with the E450 V10 setup? I'm willing to learn something new if it means getting better diagnostic capability. …more

How to Fix Onan QD3200 Diesel Generator Fuel Leak Behind Air Filter

According to Murphy's Law, my Onan QD3200 generator is doing something bizarre — it's leaking diesel fuel from behind the air filter instead of where you'd normally expect fuel leaks. The fuel appears to be coming from somewhere behind the air filter box, and I'm worried about making things worse if I don't diagnose this properly. I've shut everything down for now because I'm nervous about safety issues.

I need to know the safest way to trace where this leak is actually coming from without creating a fire hazard or damaging anything. What are the most likely culprits in that area, and what's the proper procedure to identify the exact source? I want to make sure I approach this methodically rather than just poking around and potentially making the problem worse. …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

Cummins Onan Generator Service: What to Do When Dealers Won't Service

Called three Cummins dealers about servicing my 12-year-old Onan generator and they all said it's "too old," but my neighbor's same-age unit gets serviced just fine. My generator is about 12 years old and needs some work done on it.

I'm feeling a bit overwhelmed - are there other options for getting older Onan generators repaired? I'm worried I won't be able to find anyone to work on it or get parts. Any guidance would be really appreciated since I'm not sure where else to turn for service on older equipment like this. …more

How to Convert Propane RV Generator to Diesel: Complete Fuel System Guide for Safe Installation

Before our two-week cross-country RV trip next month, I need to figure out this propane-to-diesel generator conversion because I'm getting conflicting advice and hearing horror stories about fuel starvation. My biggest concern is that if I just tap into the main fuel line with a simple tee fitting, I might end up starving either the engine or the generator when they're both running.

I'm worried I could damage something expensive or even create a dangerous situation. What are the proper ways to set up the fuel delivery system for a diesel generator conversion? I definitely don't want to just wing this - I need to know the safe, correct methods before I attempt anything. Should I be looking at a completely separate fuel system or are there ways to safely share the main tank? …more

DPF Failure Code: Repair Cost & DIY Options for RV Diesel

DPF Failure Code: Repair Cost & DIY Options for RV Diesel

According to my diagnostic scan the DPF failure code shouldn't be appearing since regeneration happened just 500 miles ago on my 2022 Holiday Rambler Cummins B6.7. Local Freightliner service center is quoting $6,400 for complete DPF replacement at 38,000 miles.

Before proceeding with this expensive repair, I need to verify: Is this quote within normal range for dealer pricing? Should my 2022 engine still have emissions warranty coverage that would apply to DPF failure? Are there alternative repair options like professional cleaning that might resolve the issue without full replacement?

Looking for technical guidance on the most cost-effective approach to address this DPF failure code before committing to the quoted repair. …more

Why Your RV Generac Diesel Generator Shuts Off After 2 Minutes Under Load: Troubleshooting Guide

Found that ever since those heavy rains last month hit, my 2007 Alfa's Generac 7.5kw diesel generator shuts down exactly 2 minutes after firing up the basement AC.

Just did a full service (oil, filters, the works) so it's not basic maintenance stuff. I can restart it right after it shuts off, but if the AC is still calling for power, it dies immediately again. No error codes or blinking lights to give me a clue.

Is this a fuel delivery issue where it can't keep up with the AC load? Or am I looking at something else entirely? Really hoping someone's dealt with this exact same 2-minute thing before! …more
