Why Do My RV Tank Sensors Read Wrong?
RV tank sensors usually read wrong because waste and tissue coat the sensor probes, not because the sensors failed. Here's how to tell the difference and what actually fixes it.
Read the guideIn Texas, the maintenance items that matter most are roof sealant, air conditioning, tires and batteries — because heat and UV degrade all four faster here than in milder climates. A workable schedule is: filters monthly, seals and tires seasonally, and a full systems inspection annually, timed for spring before the first hot week.
Why Texas is harder on an RV
Sustained heat and intense UV are the two variables that age an RV fastest, and Central Texas delivers both. Roof sealant that might last three years in a temperate climate can crack in eighteen months here. Batteries lose capacity faster. Tires age out well before the tread wears out. Air conditioners run at maximum load for months rather than weeks.
None of this is cause for alarm. It just means the maintenance intervals published in your owner's manual, which were written for average conditions, are optimistic for where you actually live.
Monthly, during use
- Clean or replace A/C return air filters — the most skipped item and the cheapest
- Walk the interior barefoot checking for soft floor spots
- Check tire pressure cold, including the spare
- Test smoke, LP, and carbon monoxide detectors
- Run the generator under load if you have one
Seasonally
- Inspect roof sealant at every seam and penetration; reseal anything cracked or lifting
- Clean condenser coils on the roof, more often in cottonwood season
- Inspect and lubricate slide seals and mechanisms
- Check battery water levels on flooded lead-acid, and clean terminals
- Inspect under sinks and behind the water heater panel for slow leaks
- Treat holding tanks and verify your monitor readings are still accurate
Annually
- Full roof inspection and reseal as needed
- LP gas system leak test and regulator pressure check
- Wheel bearing and brake inspection (we refer this to a chassis shop)
- Water heater flush and anode rod replacement where fitted
- Complete systems inspection — electrical, plumbing, appliances, roof and seals
- Holding tank deep clean, or twice a year for full-timers
Two Texas-specific items worth flagging
Tires age out before they wear out. RV tires should generally be replaced at five to seven years regardless of tread, and Texas heat pushes toward the short end. Check the DOT date code on the sidewall, not the tread depth. A blowout at highway speed does more damage to an RV than most collisions.
Winterization still applies here. Central Texas gets hard freezes, and they arrive quickly. A single unprotected night can split a water line, a pump housing, or a water heater — a repair that dwarfs the cost of winterizing. If you are not using the RV through winter, protect it.
Where owners lose the most money
Nearly every expensive RV repair we see traces back to a deferred cheap one. Roof sealant not maintained becomes floor rot. Filters not cleaned become a failed compressor. Tank treatment skipped becomes a professional cleaning. Tires kept an extra season become a blowout that tears up the underbelly.
Maintenance is not the exciting part of RV ownership. It is, reliably, the difference between a rig that lasts and one that gets sold cheap at eight years old.

Questions
Frequently Asked
Inspect every six months and plan on resealing seams and penetrations roughly annually. Texas UV degrades sealant faster than the intervals most manufacturers publish.
Yes, if it will sit unused through winter. Central Texas gets hard freezes, and one unprotected night can split water lines, the pump, or the water heater.
Five to seven years from the DOT date code on the sidewall, regardless of remaining tread. Heat accelerates the aging, so the shorter end of that range is safer here.
Filters, tire pressure, detector tests, visual seal inspections, and tank treatment are all reasonable DIY items. LP gas testing, roof resealing, and electrical diagnosis are better left to a trained technician.
