Mobile RV Pre-Trip Inspection Across Florida

What Gets Checked Before a Long Road Trip

A pre-trip inspection before a significant drive is not the same as a walk-around in the driveway. The technician checks tire pressure at cold inflation against the placard specification for the loaded vehicle, not a general recommendation. Hitch connection is verified with a torque wrench on ball mount bolts and a physical tug test on the coupler latching mechanism. LP is pressure-tested at the regulator output and all appliance valves are confirmed closed for travel.

Battery state of charge is measured under load, not just by voltage. Slide-outs are cycled to full extension and full retraction while listening for motor strain or seal drag. All exterior running lights, turn signals, and brake lights are confirmed operational. The roof is walked if access permits to check that all vents are closed and no sealant has opened since the last inspection. Mirrors and cameras are confirmed in adjustment. The coach is cleared to leave with a written sign-off.

Why RV Tires Fail More Often in Florida Heat

The failure mechanism for most Florida RV tire failures is internal heat buildup, not external puncture. An under-inflated tire flexes excessively on each rotation, and that flexing generates heat in the sidewall. At ambient temperatures that already run in the 90s in Florida summer, the additional heat from under-inflation pushes the tire compound past its thermal design range. Failure typically occurs after a sustained high-speed run rather than immediately.

The second Florida-specific factor is UV degradation of sidewall rubber. Florida's UV index is among the highest in the continental United States, and RV tires stored outdoors without UV covers lose sidewall elasticity significantly faster than the six-to-ten-year replacement schedule suggested by manufacturers for cooler climates. A tire that passes the tread depth standard but has sidewall cracking is a failure risk regardless of tread remaining. We evaluate both during a pre-trip inspection.

Checking the Brakes on a Towable Before a Trip

Electric trailer brakes require correct output from the tow vehicle's brake controller, and that controller needs to be calibrated for the loaded weight of the trailer at the time of towing - a setting that many owners configure once and never revisit as loads change. An under-calibrated controller delivers insufficient brake force; an over-calibrated one causes wheel lockup that can destabilize the combination.

Brake controller calibration is a fifteen-minute process at the tow vehicle using a multimeter and a controlled brake application. We also verify that the trailer brake wiring harness connection is clean and secure, that the breakaway switch cable is properly connected and routed, and that the breakaway battery is charged. On coaches with hydraulic surge brakes, the actuator fluid level and seal condition are checked instead.

Correct Tire Pressure for Your RV

There is no universal correct pressure for an RV tire, and the sticker inside the tow vehicle door does not apply to the trailer or motorhome. Correct cold inflation pressure for an RV tire is determined by the actual axle load at the time of travel, looked up in the load and inflation tables published by the tire manufacturer for that specific tire line. The maximum pressure on the tire sidewall is a maximum, not a target.

Most Class A motorhomes with rear tag axles and loaded weights over 25,000 pounds run rear tires in the 105 to 120 PSI range. Travel trailers in the 8,000 to 12,000 pound range typically run in the 65 to 80 PSI range. Five-wheels vary significantly by axle configuration. We measure actual cold pressure before the inspection, look up the correct target for the tire and approximate load, and adjust accordingly. Pressure is always set cold, at least three hours after the last move.

LP Checks Before a Long Drive

Before any trip, the LP system should be in a specific travel configuration: all appliances off at the appliance switch, not just at the thermostat, and the main LP tank valve positioned according to the coach manufacturer's recommendation. Most manufacturers recommend leaving the LP valve open during travel to power the refrigerator in LP mode, but some recommend closing it for tunnel compliance or ferry crossing. Know what your coach requires.

The check that matters most before a long drive is confirming that the regulator pressure is correct and that no appliance has a slow gas leak at its control valve - a condition that can allow LP to accumulate in the coach interior during travel. A pressure gauge at the inlet side of the two-stage regulator and a combustible gas sniffer at each appliance valve connection takes about fifteen minutes and gives definitive clearance.

How Long a Pre-Trip Inspection Takes

A standard pre-trip inspection takes 90 minutes to two hours. An abbreviated pre-trip covering only the highest-priority items - tires, hitch, LP shutoff confirmation, lights, and mirrors - can be done in 45 to 60 minutes for owners who have already done a maintenance inspection recently and just want a final departure check. We offer both options and will recommend the appropriate scope based on how recently the coach was last professionally inspected.

For spring departures after a coach has sat through winter storage, a combined pre-trip and dewinterization service is the most efficient approach. Dewinterization addresses the plumbing and LP system restart, and the pre-trip inspection covers everything else in the same visit. That combined service typically runs three to four hours and replaces the need for separate appointments.
