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

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

How to Fix RV Transfer Switch Not Detecting External Generator - Complete Troubleshooting Guide

The automatic transfer switch on my 1999 American Eagle detects shore power and onboard diesel genset fine, but won't recognize my external portable generator — can I fix this for under $50? The generator runs fine and produces power, but the transfer switch doesn't trigger to use it.

What causes this issue and what are my options to get the ATS to work with an external generator? …more

Motorhome vs Toy Hauler Electrical Systems: Complete Comparison Guide

Walked into three dealerships with my $40k budget and they're all pushing different electrical setups — can't afford to buy wrong between motorhome vs toy hauler power systems. Currently I have a 2020 F350 diesel SRW with a Reflection 29rs toy hauler, and I'm comparing a Grand Design Lineage 31ZW Super C motorhome versus a Momentum 381MS toy hauler.

The toy hauler I'm considering comes with serious electrical upgrades - 2 heated 400Ah lithium batteries with internal BMS, dual 3,000kVA inverters, four 300W bifacial solar panels, dual 50A solar controllers, and 60A DC-DC truck charging. Currently, to transport my side-by-side (SxS), I need two trucks and two trailers, which is inefficient.

I'm weighing pros and cons like overall length (truck and toy hauler would be about 60', MH and 20' cargo trailer would be about 57'), maintenance costs of keeping two diesel trucks, and transportation flexibility. I also have an F150 that could potentially serve as a toad vehicle.

What experiences can others share about transitioning between these RV types, especially considering power management and transportation logistics? …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

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

Southwire EMS Built-in vs External Surge Protector: Do You Need Both?

Opened my 2022 Holiday Rambler 38N DP and discovered it's eating through surge protectors way faster than normal, despite having the built-in Southwire system. Dealer says I might not need an external surge protector like a Watchdog since it's already built in.

Does a built-in Southwire surge guard provide the same protection as a standalone EMS unit? Should I still install an external surge protector or is the built-in system sufficient? Want to make sure I have proper protection without buying unnecessary equipment. …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

Complete Luxury Motorhome Buying Guide for Retirement Full-Time RV Living & Travel

My husband just casually mentioned we're about to drop our entire retirement nest egg on a luxury motorhome when neither of us knows anything about RVs.

I keep hearing different brand names thrown around but honestly have no clue which ones give you the most bang for your buck in that mid-range luxury space. Also wondering if I should buy new or let someone else take the depreciation hit? And what features should I absolutely not compromise on for full-time living?

Just want to make sure I'm not learning expensive lessons after I hand over the cash! …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

Class A vs Class C RV: Complete 2024 Buyer's Guide & Size Comparison for Beginners

Staring down the RV lot this Saturday — should I be zeroing in on Class A or Class C models for my first purchase? I'm located in Georgia and looking for a Class A or Class C motorhome in the 28-33 foot range, with specific needs for my situation.

I keep reading that Class A RVs have more space and amenities, which sounds appealing since I want things like a king bed, a 30x36 shower, and room for recliners. But I also hear that Class C motorhomes are easier to drive and get better gas mileage, which might be important since I'm not super confident behind the wheel of a big rig yet.

I'm debating between diesel or gas engines, and whether to look at pre-covid models from established brands like Newmar and Tiffin, or newer options from Entegra and Coachmen. My budget is flexible, but ideally under $100,000.

I'm planning to tow a mid-sized SUV and take both short weekend trips and longer cross-country adventures, and I'll need space to store my recumbent trike. Would really appreciate some guidance on which type would be the better fit for my situation and skill level. Should I prioritize the extra space or the easier driving experience? …more

RV Fuel Filter Replacement: How Often & Maintenance Guide

RV Fuel Filter Replacement: How Often & Maintenance Guide

Every time we plan a big RV trip, something goes wrong - and now my 2005 Tradition 40W motorhome is running rough with fuel delivery issues just days before our two-week cross-country adventure. We're fairly light users - only putting about 1,200 miles on it annually since we mostly use it for shorter trips and occasional longer vacations. The coach has two fuel filters that I can see: a Luber Finer LFF1003 and an LF5488. I'm not entirely sure when they were last changed, possibly not for quite some time.

I've been researching maintenance schedules and seeing conflicting information about fuel filter replacement intervals. Some sources suggest every 10,000 miles, others recommend annual replacement regardless of mileage. Given our low annual mileage, changing them every year seems excessive and potentially wasteful. Our local RV service shop does annual maintenance including oil changes and general inspections, but they haven't specifically flagged the fuel filters as needing replacement.

What would be the appropriate replacement interval for fuel filters on a low-mileage RV like ours? Should I be concerned about contamination or other issues even with light use? I want to maintain the engine properly without over-maintaining components that don't need frequent attention. …more
