Cummins ISL Code 1896: EGR Valve Controller Gaskets & Repair

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.

Do I need to order replacement gaskets before I start this job? Want to make sure I have everything on hand before I tear into it. …more

Onan Generator Fault Codes: Complete Troubleshooting Guide for RV Owners

During my latest camping trip my Onan generator threw a fault code — got my multimeter ready and just need to figure out which diagnostic approach will crack this thing.

I'm seeing 12 or 13 blinks on my generator error display and want to understand what these codes might mean. Are these codes consistent across different Onan models? I'm hoping it's a minor issue and not something requiring a major repair.

Can anyone help me decode what these blinking fault codes typically indicate? …more

Ford F53 V10 Bypass Oil Filter Installation: Best Mounting Locations for RV Chassis

Walked out to check my oil analysis results and they're showing 15-micron contaminants, but everything says my 2003 F53 V10's factory filter catches down to 25 microns. I've been reading about how these can help extend oil life and keep things cleaner, but I'm honestly not sure where the best place to mount one would be.

I've seen some people mention sandwich adapters at the original filter location, remote mounting blocks, and even tapping directly into the engine block. As someone who's still learning, I don't want to mess this up or create problems down the road. What's considered the best practice for mounting location on the F53 V10? I'd really appreciate some guidance from those who have done this before. …more

Onan 5500 Generator Tune-Up Guide: Best Aftermarket Parts & Filters 20

Before my last camping trip when I tried to order replacement parts, I discovered that finding genuine OEM components for my Onan 5500 generator has become nearly impossible. The Cummins website has been showing most tune-up components as out of stock for months now, and when I do find supposedly "official" Onan oil filters online, many retailers are substituting generic filters that may not meet the same specifications.

I've been researching alternatives and I'm particularly concerned about getting the right oil filter and spark plugs. For the oil filter, I've seen conflicting information about whether aftermarket options like Wix filters are truly compatible - some sources mention the 57398 but I've read mixed reviews about fitment issues. For spark plugs, my current ones are NGK BPR4EY, and I've heard the NGK 3432 might be equivalent, but I want to make sure before ordering.

I'm also planning to stick with zinc-containing oil like Rotella T6 15w40 since I know air-cooled engines need the extra protection, but I'd love confirmation that I'm on the right track with quality aftermarket parts that won't compromise my generator's performance. What specific part numbers and brands would you recommend for a reliable tune-up when OEM parts aren't available? …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

E450 V10 Air Filter: How Often to Change on Dusty Roads

Every Saturday I'm planning to tackle my Ford E450 V10's air filter after months of dusty backroad camping — what maintenance schedule should I actually follow? The owner's manual suggests changing the air filter every 30,000 miles, but that seems like a really long interval to me.

I do a fair amount of camping on dusty dirt roads - probably covering about 8-16 miles per month on these conditions to reach remote campsites. I'm worried that all that dust might mean I need to change the filter more frequently than what Ford recommends.

Should I be following a different maintenance schedule given these dusty conditions? And is there anything I should be doing between filter changes to keep things running smoothly? I want to make sure I'm taking proper care of this engine but don't want to over-maintain either. …more

Onan 7500 QD Code 36 Fix: How to Solve Generator Overfill Oil Shutdown Problems

Woke up this morning to fire up my Onan 7500KW QD for camping season, and that dreaded Code 36 shutdown nightmare is back again. I can restart it after waiting a bit, but this is driving me nuts.

I've been digging around online and came across something weird - apparently these dipsticks are calibrated wrong? Some folks are saying you're supposed to keep the oil level just above the 'ADD 1QT' mark instead of at the full line to avoid overfill shutdowns. That sounds backwards to me, but I'm seeing it mentioned everywhere.

Before I start messing with oil levels or throwing money at fuel pumps and control boards, can anyone confirm if this dipstick thing is actually legit? Really hoping it's something this simple! …more

Onan 4KY Generator Starts Then Dies: Oil Pressure Sensor Troubleshooting Guide

About to sound like a total newbie here, but why does my 2018 Winnebago Spirit's Onan 4KY-26100R generator start perfectly then instantly die when I release the start switch? I suspect it's the oil pressure sensor based on what I've read, but want to confirm this diagnosis before ordering parts. Oil level appears normal. I've tried locating the oil sensor near the oil filler tube on the crankcase, but it's difficult to see or reach. Is there a way to test if the oil pressure sensor is actually the problem? Can I bypass it temporarily to verify that's the issue? …more

RV Fresh Water Tank Safety: Complete Guide to Preventing Contamination Risks

Between the horror stories about brain-eating amoebas and my complete cluelessness about RV water systems, I'm terrified I'm going to poison myself with my own fresh water tank. I've been RVing for years and never really thought twice about our fresh water tank - we'd fill up wherever, use it for drinking, cooking, even my wife's neti pot rinses.

Now I'm second-guessing everything! How often should I actually be sanitizing our tank? Are there specific water sources I should avoid? And what about activities like nasal irrigation - I keep seeing conflicting advice about what water is actually safe to use. I really want to keep my family safe but also don't want to become completely neurotic about every drop of water we use. What are the real best practices here? …more

Onan Generator Won't Stay Running: Complete Repair vs Replace Guide 20

Three distinct sputtering sounds keep coming from my Onan generator that fires up perfectly but dies out after running for a while. Multiple service calls and repairs have been attempted, but the problems persist intermittently, making diagnosis challenging.

The repair costs are accumulating significantly, and I'm reaching a decision point regarding whether to continue troubleshooting or consider replacement options. What criteria should I use to determine when total repair investment justifies switching to a replacement unit? Are refurbished Onan generators a viable alternative, and what factors should guide this repair-versus-replace analysis for intermittent generator failures?

(Note: This is specifically about my RV's Onan generator, which I'm referring to as my 'Jenny'.) …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

Airxcel Furnace Not Working When Thermostat Switched to Heat

Looked everywhere for answers but my 2019 Forest River with an Airxcel furnace won't kick on when I switch the thermostat to heat mode. When I turn the thermostat to heat mode and adjust the temperature setting, absolutely nothing happens - no sounds, no fan activation, no ignition attempts, nothing at all. The unit was working perfectly fine last month during our camping trip, but now it's completely dead when I try to activate it through the thermostat.

I've tried adjusting the temperature settings both higher and lower, checked that the thermostat is properly set to heat mode rather than cool or off, and even tried turning the system off and back on again. The thermostat display appears to be functioning normally and shows the temperature settings I'm selecting, but the furnace itself shows no signs of life whatsoever. I'm wondering if this could be an electrical issue, a propane supply problem, or something with the connections between the thermostat and the furnace unit itself. …more

Monaco Knight 40 Fuel Economy: Real MPG Numbers When Towing a Car

Our 2012 Monaco Knight DFT 40 GOLD is sitting in the driveway right now with the Jeep hitched behind it, and I can practically see my wallet getting lighter just looking at this setup. We're looking at covering about 1000 miles over the course of the trip, and I'm trying to get realistic expectations for fuel costs and planning fuel stops accordingly.

I've heard wildly different numbers from other RV owners about what kind of fuel economy to expect when towing a vehicle behind a 40-foot diesel pusher like the Monaco Knight. Some people claim they get decent mileage, while others say it's absolutely terrible. I'd love to know what's actually realistic to expect in terms of MPG when towing, and if there are any driving techniques or speed considerations that can help maximize fuel economy on a long trip like this. …more

2000 Ford E450 V10 Uphill Power Mods for Mountain Towing

Called three different YouTube tutorials claiming to boost my 2000 Ford E450 V10's uphill towing power, but now my motorhome struggles even worse in the mountains. The unit struggles substantially on extended uphill grades, particularly during Rocky Mountain travel where sustained climbs can last 30+ minutes.

I'm evaluating several modification options to address this performance deficiency: rear differential gear ratio changes, SCT programming modules, K&N high-flow air filtration systems, and catalytic converter removal. I need to understand which modifications will provide measurable uphill towing improvements versus those that offer minimal gains.

What is the relative effectiveness of these power modifications for V10 mountain towing applications? I'm looking for a technical assessment of which upgrades deliver the most significant performance improvements for this specific application. …more
