The Pre-Keys Trip Trailer Checklist

The drive from Miami down to the Keys is one of the best tows in the country and one of the worst places to break down. Long stretches of US-1 with narrow shoulders, summer heat, weekend traffic, and not much between Florida City and Key Largo. We rescue trailers on that road every week, and most of those calls trace back to something a ten-minute check would have caught in the driveway.

Here's the check we'd run on our own trailer before any Keys trip.

Tires: check the date, not just the tread

Trailer tires age out before they wear out. Find the DOT date code on the sidewall; the last four digits are the week and year the tire was made. Past five or six years, replace it no matter how good the tread looks. Florida sun cooks sidewalls from the outside while the tire sits.

Then check pressure cold, to the max pressure printed on the sidewall. Underinflated trailer tires run hot, and heat is what blows them on a loaded summer tow. Look for sidewall cracking and bulges while you're down there. Uneven wear across the tread usually means an axle or suspension problem, and that's worth a call before the trip, not after.

Bearings: the hand test

Tow the rig a few miles, stop, and put a hand near each hub. Warm is fine. Too hot to touch means trouble. Jack each wheel and rock it top to bottom; any play or clunk means the bearings need attention. If the trailer launches in saltwater and hasn't had a repack in the last year, do it before this trip.

Lights: full circuit

Plug in, then walk the trailer with a helper working the truck: running lights, both turn signals, brake lights. Fast blinking on the dash usually means a dead bulb or bad ground on the trailer side. A green, corroded connector at the hitch is the most common cause of lights that work in the driveway and quit an hour later.

Coupler, chains, and jack

Drop the coupler on the ball and confirm it latches all the way, then lift the tongue jack briefly; if the coupler climbs off the ball, it's not latched or it's worn. Cross the safety chains under the tongue and check the links and hooks for rust and stretch. Test the breakaway cable if you have brakes. Make sure the jack cranks freely and stows fully up.

Winch and tie-downs

Check the winch strap for fraying, snug the bow against the stop, and confirm the transom straps are tight and not sun-rotted. The trailer holds the boat going forward. The straps hold it everywhere else.

The spare

An actual spare, mounted, with air in it, in the right size. Plus a lug wrench that fits the trailer's lugs (they're often not the same as your truck's) and a jack that can lift a loaded trailer. Half the blowout calls we run are for trailers with no usable spare aboard.

If something fails the check

Give us a call before you go. We come to your driveway, marina, or storage lot anywhere in Miami-Dade and fix it there, so the problem gets solved on your schedule instead of on the shoulder at Mile Marker 110.

And if something lets go on the road anyway, we answer 24/7 and we run rescues on the Keys stretch all the time. Save this number before you hitch up: (786) 570-9538.
