Snowbird Season: RV Breakdowns on the Panhandle Run

Every fall the same wave comes down I-10, and every spring it goes back up. Big diesel pushers, thirty-foot travel trailers, fifth-wheels with a golf cart on the back. Most of them make it fine. The ones that do not break down for the same handful of reasons, and nearly all of those trace back to the rig sitting still for six or eight months.

Sitting is what kills RVs. Not miles.

The run everybody makes

Coming into the panhandle, most rigs are on I-10 from the east or west, then peeling off south. US-90 through Milton and Pace. US-98 along the coast. The bridges over to Gulf Breeze, Navarre Beach, and Pensacola Beach. Then months parked, and the whole thing in reverse in the spring.

Two things about that route matter. I-10 moves fast out here, and the shoulders are narrower than they look when you are standing next to a forty-foot coach. And the bridges have essentially no shoulder at all. A bridge span is also exactly where a struggling rig tends to finally quit, because you have been climbing a grade with the engine loaded.

If the rig starts acting up as you come up on a bridge, get all the way across and off before you stop. Stopping on a panhandle bridge span means sitting in a live lane with nowhere for anyone to go around you.

What six months of sitting does to a rig

This is the actual root cause of most snowbird breakdowns. The rig was fine when you parked it. It is not fine now.

• Tires. The big one. RV tires age out on sidewall dry rot long before the tread wears down. Sitting is worse than driving: full weight rests on one flat patch, the rubber never flexes, and Florida sun pulls the protective oils right out of the sidewall. A tire with 90 percent of its tread and seven years on the date code is waiting to let go on a hot afternoon.
• Batteries. A lead-acid battery left partially discharged for months sulfates and permanently loses capacity. Left connected to the parasitic loads in an RV, it slowly drains to nothing and sits there dying.
• Brakes. Drums rust, shoes stick to drums, electric brake magnets corrode. A trailer that sat all summer in humidity often tows away with brakes that grab on one side or do not work at all.
• Fuel. Ethanol gasoline goes bad and gums up carburetors, which mostly bites you on the generator. Diesel that sat can grow algae and plug filters.
• Belts and hoses. Rubber that baked in heat gets hard and cracked, and the first real load on the interstate is when it lets go.
• Rodents. Wiring harnesses and insulation are chew toys, and this one is maddening to diagnose after the fact.
• Roof sealant. Southern heat and UV cook it. The leak starts while you are parked and you find it while you are driving.

The pre-departure check that catches most of it

Do this a week before you leave, not the morning of. If you find something, you want time to fix it.

1. 1Read the DOT date code on every tire, including the spare. The last four digits are the week and year it was built. Inspect closely past five years, replace at seven regardless of tread, and look hard at the sidewalls for fine spiderweb cracking.
2. 2Set every tire to cold pressure with a real gauge, matched to what the rig actually weighs, not the maximum on the sidewall.
3. 3Check the batteries. Resting voltage on a 12-volt battery should be around 12.6, and flooded batteries need their water topped off.
4. 4Test the trailer brakes with the manual override lever on your controller at low speed. You should feel the trailer drag the rig down. If not, do not tow it.
5. 5Run the generator under load for a couple of hours, before you need it in a rest area at midnight.
6. 6Check belts, hoses, coolant, and oil, and look under the rig for anything hanging, dripping, or rubbing.
7. 7Grease the suspension pivots, and look for cracked leaf springs and cracked hanger welds.
8. 8Grab each wheel top and bottom and rock it. Any play means a bearing or bushing wants attention before you go.

Where things go wrong out here

Panhandle heat is a tire problem first. Summer pavement gets brutally hot, and a tire a few pounds low builds heat fast. Underinflation plus heat plus an old casing is the exact recipe for a blowout, and it is the single most common thing that puts an RV on the shoulder of I-10.

Heat also finishes off marginal cooling systems and marginal batteries. A battery rarely dies on the coldest day. It dies after a summer of being cooked, and then it will not crank on the first cool morning.

Salt air is the other local special. If your rig spends the season near the water at Navarre, Pensacola Beach, or Gulf Breeze, corrosion works on everything metal, and it works hardest on electrical connectors, brake components, and the seven-way plug at the tongue. Owners who come down from Michigan are always surprised by it.

If you break down on the panhandle

Get as far off the pavement as the shoulder allows. Hazards on. Warning triangles out well behind you, and put them out before you start looking at anything. Everybody exits on the passenger side, away from traffic, and gets behind the guardrail or up the bank.

Then think about what you actually need. A blown tire, a dead battery, a fuel problem, an air leak, a bad alternator, a slide that will not come in, a seized brake: none of those require a tow. They require somebody to come to you with parts and tools. Towing a forty-foot coach is slow, expensive, and usually unnecessary.

Duckett Roadside Repair is based in Milton and works the whole panhandle: Pace, Bagdad, Pensacola, Gulf Breeze, Navarre, Crestview, Fort Walton Beach, and the I-10 corridor in between. Mobile RV, camper, and truck repair, which means the truck comes to your shoulder or your campsite instead of hauling you off somewhere. Call (850) 495-0366 any hour of any day. Give dispatch your mile marker and direction of travel, and stay behind the guardrail until somebody gets there.
