What exactly gets inspected and fixed in an RV propane system?

Your RV propane system has a dozen connection points, and we service every one. We replace regulators - both high-side Truma and Atwood units - test all lines for leaks using electronic detection, certify your system pressure (safe range is 11-13 PSI for low-pressure appliances), repair or replace copper and steel line sections, rebuild switchover valves so both tanks feed reliably, inspect low-pressure safety detectors, secure tank tie-downs to frame, and confirm every connection from tank valve to furnace inlet. We've serviced over 12,000 RVs in 15 years. One inspection catches problems before they strand you.

A Grand Design owner from Jacksonville called us last month - her furnace wouldn't ignite, and she'd been sitting dead in a Camping World lot for three days. Turned out the low-pressure detector on her Dometic regulator had corroded. We pulled the old unit, bench-tested it (failed), installed a new Truma regulator, certified the line pressure, and she had heat again in 90 minutes. No shop visit needed. That's the difference between mobile and waiting for a service bay.

What are the most common propane system failures we see?

Leaks, corrosion, and regulator drift cause about 80% of RV propane problems. Copper lines corrode from humidity - especially in coastal Florida - and pinhole leaks develop where you can't see them. Regulators fail when internal seals wear out or moisture gets inside. Switchover valves stick, trapping you on one tank. Low-pressure detectors (safety switches that cut gas if pressure drops) get dirty or lose sensitivity. Tank tie-downs loosen from road vibration, letting the tank rock and strain connections. We've pulled propane-soaked insulation from under RVs where a fitting slowly leaked for months. Electronic leak detection catches all of it.

A Winnebago traveler heading from Boise to Coeur d'Alene called us smelling rotten eggs - classic propane odor additive warning. We arrived, ran our electronic detector, found a pinhole leak in the low-pressure line behind the water heater. The line had been flexing against a mounting bracket for two years. We replaced the section with a new Shurflo-grade copper line, pressure-tested the whole system, certified it, and he rolled out confident. Cost was $240. Dealer would have kept him parked for a week.

How much does propane system service cost, and how is pricing structured?

We quote all work flat-rate by phone - no surprise invoices. Regulator replacement runs $180 to $320 depending on brand (Truma costs more than Atwood, but lasts longer). Leak detection and certification: $95. Line repair or replacement: $120 to $180 per section. Switchover valve rebuild or replacement: $140 to $250. Low-pressure detector replacement: $85 to $130. Tank tie-down repair: $65 to $110. A full system inspection with pressure test and documentation: $150. Most customers spend $300 to $550 for a complete overhaul. We don't charge by the hour. You know the cost before we touch anything.

A Keystone owner in Tampa had three failures at once - regulator leaking, low-pressure detector dead, tie-down bracket cracked. We quoted her $585 over the phone: $240 (Atwood regulator), $110 (low-pressure detector), $85 (tie-down bracket and fasteners), $95 (full pressure test and certification), $55 (trip charge). She approved, we showed up next morning, finished in 2.5 hours, and she had heat and hot water again. No hourly meter running. No dealer pricing games.

How fast can you get to my RV, and what about nights or weekends?

We hit 2 to 4 hour response in core Florida and Idaho areas during business hours - that's mobile advantage. No waiting for a service writer, no slot three weeks out. We roll to you with tools and parts. Emergency calls (no heat, smell, obvious leak) get priority dispatch. Standard work books same-day or next-morning depending on volume. Nights and weekends: we take calls 24/7, but dispatch depends on staff availability in your zone. During high season (December-March in Florida), demand is heavy - call early. You get a flat quote by phone, confirm the price, then we lock in a 2-hour window. After-hours emergency repair carries a $75 surcharge, but you're not stuck on the side of I-75.

A Forest River owner outside Ocala had a regulator leak at 10 PM on a Saturday - propane smell in the cabin, kids nervous. She called (888) 787-3727, we heard the urgency, sent a truck at 10:45 PM. Tech arrived at 11:30, diagnosed a failed Atwood regulator seal, had a replacement Truma unit in stock, and system was certified by 12:40 AM. She paid the flat rate ($280) plus the $75 emergency surcharge. Worth every penny for peace of mind in the dark.

Which propane regulator brands work with my RV, and do we stock them?

We work on Atwood, Truma, and Dometic regulators - the three brands covering 95% of RVs. Atwood is OEM on Forest River and Coachmen rigs; solid, affordable, parts plentiful. Truma (German-engineered) comes on Airstream, Tiffin, and premium units - more expensive but bulletproof reliability. Dometic shows up on Jayco, Keystone, and some Grand Design models. We stock Truma and Atwood units on our trucks. Dometic we can usually get same-day. Know your RV year and make before you call - we'll confirm the regulator brand in 30 seconds. Don't assume what's on your rig.

A Tiffin customer thought she had a standard Atwood regulator - that's what the dealer told her five years ago. When it failed, we arrived with an Atwood replacement, then realized her 2019 Phaeton actually came with a Truma from factory. We swapped the truck stock for a Truma, installed it, and called ahead to confirm availability. Truma runs $280, Atwood runs $195, but she got the right part and a two-year lifespan difference. Always verify before we roll.

Common RV brands and their regulators:

What happens after you finish the repair - how do I know the system is safe?

You get a pressure-certified system and written documentation. After every regulator, line, or detector job, we run electronic leak detection on the entire system, measure pressure at the regulator outlet (must be 11-13 PSI for safe appliance operation), confirm switchover function, and test the low-pressure safety shutoff. We print a certification sheet with pressure readings, component brands, and work performed - handy for insurance or if you ever resell. Everything comes with a 90-day workmanship warranty: if a regulator we installed fails within 90 days due to our install, we fix it free. You leave with a system you can trust.

A Jayco owner asked us to stay while she tested the furnace, stove, and water heater after we finished a full regulator and line job. We certified pressure at 12.1 PSI (dead in spec), watched all three appliances light cleanly, and handed her the certification card. She kept it in her RV folder. Three months later, she sold the rig - the new owner felt confident because that card proved the gas system had been properly serviced. That's what a real warranty looks like.
