LiFePO4 Battery Not Charging in RV: Complete Diagnosis Guide 2024

Planning my next boondocking trip when this faint electrical burning smell started coming from my battery compartment, and my 950W flat mounted plus 1200W ground solar setup isn't charging my LiFePO4 batteries at all. My LiFePO4 batteries used to charge up beautifully, hitting 100% by late afternoon like clockwork.

Now? Total drama queens. This morning we woke up at 18% charge, and after a full day of glorious sunshine, we're sitting pretty at a whopping 63%. With 2150W of solar, I should be swimming in electrons! But instead my batteries are acting like teenagers - moody and refusing to cooperate.

I'm starting to suspect something's gone wrong, but honestly, I have no clue how to properly check LiFePO4 batteries. Are they actually broken, or am I just doing something monumentally stupid? What voltage readings should I be looking for, and what else should I check before I start panic-buying new batteries? …more

RV Window Seal Leaking: Complete Repair Guide & Solutions

Opened up my RV window seals yesterday thinking I fixed the leak, but water's still dripping through during today's downpour — what did I miss? The rubber seals around the frames are obviously shot, all cracked and dried out looking.

I'm torn between two approaches here: should I take the time to completely remove the old seals and put in new butyl tape/rubber sealing, or can I just run some caulk over the existing stuff and call it good? Looking for the best long-term fix that'll actually keep me dry! …more

How to Travel with a Winterized RV: Complete Cold Weather Guide

I noticed my travel trailer isn't winterized for my Connecticut to Florida Keys trip in February — can't afford professional service right now, need DIY solutions under $200? I'll be stopping at my brother's place in New Jersey first, and then caravaning to our first stop in Fredericksburg, VA at a KOA with a full bathhouse.

I've winterized my travel trailer for the cold months up here, and I recently heard a podcast about travelers staying winterized and using RV antifreeze for quick bathroom needs during the trip. I'm wondering if anyone has experience with this approach.

I know I could de-winterize before leaving, but I'm worried about pipes freezing during the drive south since we'll be going through some cold states. On the other hand, traveling winterized means no water systems working during the trip. What's the smartest way to handle this? Should I keep it winterized for the whole drive and deal with no water, or is there a better strategy I'm missing? …more

RV Engine Stalling & Transmission Issues - Diagnosis Help

Replaced multiple parts but I'm still standing in the auto parts store aisle staring at diagnostic tools with no clue which one I actually need for my RV's stalling and transmission issues. When I'm cruising and let off the gas, sometimes the RPMs drop like a rock, other times they just hang there until I slow down more. That's weird enough, but here's the real kicker - every now and then the whole engine just dies on me when I'm rolling up to a stop sign or red light. Maybe happens twice in 600 miles or so, so it's not constant but definitely not normal either.

I'm wondering if these two issues are connected somehow? Like could whatever's causing the stalling also be messing with how the transmission acts when I let off the throttle? Really hoping someone has seen this combo before because I'm in Germany and finding RV-specific help is tough.

I'm looking for any insights from folks who might know what could cause this - hoping to get to the bottom of this before it becomes a bigger problem! …more

How to Stop RV Windshield Condensation: Complete Prevention Guide

Between running my AC constantly or relying on fans and ventilation to stop windshield condensation in my 31-foot Class A during Naples' brutal 89% humidity. Experiencing persistent exterior windshield condensation at 5:15 AM, while side windows and rear bedroom window remain clear. Recently modified ventilation by closing all four interior AC roof vents to test temperature regulation effects.

Condensation appears as moderate moisture accumulation on windshield exterior surface, with minimal condensation on some side windows. This occurs during typical Florida morning conditions with significant temperature differential between nighttime glass surface and ambient air humidity levels.

Require systematic approach to eliminate both interior and exterior condensation formation. What are the most effective methods to prevent windshield fogging through humidity control, ventilation management, and thermal barriers?

Dometic CF80 Drain Foam Replacement: Complete Step-by-Step Guide

Woke up to check out my new place's Dometic CF80 basement refrigerator/freezer and discovered what looks like deteriorated foam filter stuff in the bottom drain compartment. The foam material shows significant contamination and degradation.

I need to understand the specific function of this foam component within the CF80's drainage system. Is this foam element critical for proper unit operation, and what are the consequences of operating without it? Additionally, what is the recommended replacement schedule for this component, and how do I determine when replacement is necessary versus simple cleaning? …more

RV Gray Tank Draining Slowly? Fix Clogs & Flow Issues

RV Gray Tank Draining Slowly? Fix Clogs & Flow Issues

Called around to shops about my 2019 Forest River Cherokee's gray tank drain crawling—what used to take 5-10 minutes now drags on for 30-45 minutes. The black tank still drains at normal speed, so I don't think it's a problem with the main sewer connection or hose.

I'm wondering what typically causes gray tanks to develop drainage problems over time. We do a lot of dishwashing in the RV and I'm thinking maybe grease or soap buildup could be creating blockages somewhere in the system. The flow starts out okay but quickly reduces to just a trickle, even though I know there's still plenty of water in the tank.

What are the most common culprits behind slow gray tank drainage, and what's the best approach for diagnosing and fixing these flow issues? I'd rather understand the root causes and proper solutions before I start taking things apart or using harsh chemicals that might damage the system. …more

Thetford Aurora Toilet Replacement Guide: Best RV Toilet Upgrades 2024

The minor drip from my Thetford Aurora toilet seals started last month but now it's turned into a constant leak requiring daily maintenance. After one seal replacement, the failure recurred within four months of operation, indicating a potential systemic issue with this model's design.

I'm evaluating replacement options and need technical guidance on reliable alternatives. Budget considerations are important, but I require a unit that can withstand continuous use without recurring maintenance issues. Preference is for ceramic bowl construction over plastic alternatives for durability and performance characteristics.

What are the most reliable Thetford toilet models for Aurora replacement, and how do budget options like the Aqua Magic series compare to mid-range and premium models in terms of long-term reliability and seal performance? …more

How to Find the Correct Tire Pressure for Goodyear Fuel Max RSA RV Tires

Before, my old Class C worked fine with the dealer's generic tire pressure chart — but these new Goodyear Fuel Max RSA 245/70R19.5 load range H tires on my 2008 Winnebago Sightseer 29R are completely different. My loaded RV weighs 6,020 lbs on the front axle and 11,220 lbs on the rear axle based on my most recent scale weights.

I'm concerned that 100 PSI might be too high since my previous Goodyear G670RV tires ran fine at 85-90 PSI, and the handling feels different now, especially when towing. I want to make sure I'm running the correct tire pressure based on my actual axle weights rather than just using maximum ratings or generic guidelines. What's the proper way to determine the right inflation pressure for these Fuel Max RSA tires given my specific load conditions? …more

How to Cool Hot RV Window Frames: 7 Proven Heat Reduction Solutions

Three months into owning my first RV and I'm completely lost on why these black aluminum window frames are hitting 129°F in just 90° weather. I'm pretty sure I could get a nice sear on a steak if I tried.

I'm looking for the most effective ways to tame these heat magnets before they turn my RV into a mobile sauna. I've heard about exterior reflective covers, interior solutions with Reflectix, and I'm wondering what actually works best. Should I be blocking the sun before it hits the frames, or can interior covers do the trick? And how the heck do you attach exterior covers without them flying off down the highway like aluminum kites?

Any battle-tested solutions from fellow victims of the great window frame heat conspiracy would be much appreciated! …more
Advent RV Air Conditioner Not Cooling? Complete KoolRV Adapter Fix Guide

Advent RV Air Conditioner Not Cooling? Complete KoolRV Adapter Fix Guide

Around 6 AM I walked out to my fifth wheel and spotted my Advent air conditioner running but barely pushing any cool air through the vents. I replaced my old Coleman AC with an Advent, mainly due to price, but I'm not getting good cooling during the heat of the day. I've found that opening the slide vents on the ceiling cover helps a bit.

I'm considering using a KoolRV adapter like I had with my previous Coleman, but no adapter currently exists for the Advent. I've noticed the cold air discharge opening is located in the corner instead of the center, which I think is causing air turbulence and restricting duct airflow.

My main concern is whether restricting the airflow too much could cause problems like freezing up or other damage to the AC system. I've also seen that installing these adapters involves removing some kind of dividing wall inside the unit, but I don't understand why that's necessary.

Could someone explain if there are risks to restricting airflow and why that dividing wall needs to be removed? I want to make sure I understand what I'm getting into before I try any modifications. Right now, it's starting to cool down here in the Everglades, but I still want to improve my cooling performance. Thanks for any guidance! …more

Ford E450 RV Unused Engine Bay Plugs: Complete Identification Guide

Three different Ford techs want $400 for replacing this massive electrical connector in my 2017 E450 engine bay, but it looks completely unused to me. It's our chassis for a 2018 Sunseeker 2430S-CD, and this thing has been bugging me for months now - it's just sitting there unused with no obvious purpose.

I've been all through the manuals and can't find any reference to it. The RV runs great and I don't think we're missing any functionality, but seeing this big plug just hanging there makes me worried we didn't get something we paid for or that there's supposed to be some optional equipment connected.

Has anyone else dealt with these mystery connectors on Ford E450 chassis? I really need to know what this was intended for before I drive myself crazy thinking about it! …more

Has anyone actually used the Hieha brand long-term? I'm particularly concerned about accuracy issues and whether the sensors will actually alert me when there's a real problem.

How to Properly Store RV Lithium Batteries During Wisconsin Winters: Cold Weather Care Guide

After storing my RV in freezing Wisconsin temps all winter, I just realized our Florida trip starts next month and my lithium batteries got zero cold weather prep! Got my RV winterized, but completely spaced on what to do with my lithium batteries during Wisconsin's lovely sub-zero season.

I know lithium batteries are supposedly the bee's knees compared to lead-acid, but I'm pretty sure letting them freeze solid in my garage isn't part of their charm. Should I be storing them somewhere warmer? What about charge levels - do I top them off or run them down? And please tell me I don't have to babysit them all winter long!

Could use some advice specific to RV lithium battery storage, since I didn't mention the specific battery type or RV details in my original post. …more
