RV Repair in Navarre, FL: On-Site Help for Motorhomes and Travel Trailers

Navarre runs along US-98 between Gulf Breeze and the Fort Walton Beach side, with the bridge over Santa Rosa Sound to Navarre Beach. It is an RV town for a good reason. People come here to sit by the water, and a lot of them arrive towing thirty feet of travel trailer or driving a diesel pusher that has not been out of storage since last season.

That combination generates a very predictable set of failures. Duckett Roadside Repair does mobile RV and camper service across Navarre, which means motorhomes, travel trailers and fifth-wheels get worked on where they are parked or where they quit, rather than getting hauled somewhere.

RV tires die of age, not mileage

This is the single most misunderstood thing about RV ownership, and it is the cause of an enormous number of roadside failures on 98 every summer.

Your RV tires probably have plenty of tread. They may look practically new. That is the trap. Rubber degrades over time regardless of use, and a trailer that sits in the Florida sun for eleven months a year is aging its tires the entire time it sits. UV, ozone, heat and the weight of a parked trailer pressing on the same contact patch for a year all break the tire down from the inside.

General industry guidance from tire manufacturers and RV makers commonly puts the replacement window somewhere in the five to seven year range from the date of manufacture, regardless of tread depth. Find the DOT code on the sidewall. The last four digits are the week and year it was built. A tire stamped 3419 was made in the 34th week of 2019, and it does not care how few miles you have put on it.

Check the build date on every tire before your first trip of the season, including the spare. A blowout on a travel trailer does not just cost a tire. The carcass comes apart at speed and takes out fender skirting, wiring, plumbing and sometimes the sidewall of the trailer on its way past.

The two battery systems, and why people confuse them

A motorhome has a chassis battery that starts the engine and a house bank that runs the lights, the fridge and the water pump. They are separate systems that meet at an isolator or a solenoid, and understanding which one is dead saves a lot of frustration.

• Interior lights work but the engine will not crank: chassis battery or starting circuit.
• Engine starts fine but the house is dead: house bank, converter, or the isolator that is supposed to be charging it.
• Nothing at all: main disconnect, a blown main fuse, or both banks are flat.
• Everything works on shore power and nothing works off it: your house bank is not holding a charge, which usually means it has been sitting deeply discharged and is finished.

Deep-cycle house batteries that get left flat over the winter are usually not coming back. That is a replacement, not a charge.

Trailer brakes and the wiring that runs them

Electric brakes on a travel trailer are simple until they are not. The magnet in each drum gets energized by the brake controller in the tow vehicle, and the whole thing depends on a clean electrical path through the seven-pin connector, down the frame, to each wheel.

On a coastal RV, that path corrodes. Salt air gets into the seven-pin, into the frame grounds, into the wiring where it passes through a grommet that dried out three years ago. The symptoms are recognizable: brakes that grab on one side, brakes that fade, a controller that reads no connection, or brakes that simply do nothing and you are stopping thirty feet of trailer with your truck alone.

If your tow vehicle feels like it is doing all the work, your trailer brakes are not working. Do not talk yourself out of that. It is a real safety problem and it is a fixable one.

What a mobile RV call usually turns out to be

The calls that come in from RVers around Navarre tend to fall into a handful of buckets, and almost all of them are fixable on site:

• Tire failure or a flat on a motorhome, trailer or fifth-wheel.
• Dead batteries, chassis or house.
• Alternator failure, which shows up as a rig that dies miles after the warning light came on.
• Air system problems on diesel pushers and air-braked coaches. Same physics as a truck, same failures.
• Lighting and wiring faults that will get you pulled over or fail an inspection.
• Hoses, belts, and cooling problems that show up the first hot day of the trip.
• Fuel problems, including simply running the tank empty on a long haul down 98.
• Lockouts and jump-starts.

What Duckett does not do is your house. No residential HVAC, no plumbing, no appliances, and no motorcycles. This is a mobile mechanical outfit for trucks, trailers and RVs.

Weight, and why so many rigs are running wrong

A lot of RVs are heavier than their owners believe. People load the bays, fill the fresh water tank, throw the generator and the bikes on, and never put the rig on a scale.

Every axle has a rating and every tire has a rating. Fresh water is roughly eight and a third pounds per gallon, so a full 60-gallon tank is about 500 pounds you added without noticing. Load past the ratings and the tires are what pay for it, at 65 miles an hour on the Gulf Breeze Parkway.

Before the season starts

1. 1Read the DOT date codes on every tire, spare included, and set the pressures cold to the sticker.
2. 2Load-test the batteries rather than just charging them.
3. 3Pull a drum or at least test each brake magnet before you tow anything.
4. 4Inspect the seven-pin connector, clean it, grease it.
5. 5Check belts, hoses, coolant and the generator before you need any of them.
6. 6Grease the wheel bearings on a trailer that has sat. Bearings that sat wet are bearings that fail hot.

If you are already stuck

James Duckett and his crew run mobile RV and camper service out of Milton and cover Navarre, Gulf Breeze, Pensacola Beach, Fort Walton Beach, Mary Esther and the I-10 corridor. If you are sitting on US-98 with a blown trailer tire, or in a campground with a coach that will not crank, call (850) 495-0366. Dispatch answers 24 hours a day, seven days a week, and the whole idea is to fix the rig where it sits so you can get back to what you came here for.
