I recently picked up a 1992 Pace 24' enclosed trailer. My trailer dealer buddy believes it was originally intended to be a construction business trailer, not a car trailer. It is taller than most car trailers, has no dovetail at the back and has multiple tie down rings halfway up the walls. It's not pretty but appears to be structuraly sound. After some recent hard rainstorms there are no signs of leaks even though the galvanized roof has surface rust. It has lived it's life as a car hauler though. My main purpose for buying it was hauling cars or parts to car races, shows and swap meets. It does need some upgrades though. The floor tie downs were only into the wood, not into the cross beams plus they stuck up from the floor a little. So first thing was to upgrade the tiedowns. I picked up four 5000 pound tie downs from the Pate swap meet in Fort Worth for $3 each. These were semi-recessed and I wanted full recessed. So first thing was to flaten the edge of the plate. I used my 12 ton press and by the last one was getting prety good at it. A large hole saw was used to cut two holes in the floor, a jig saw and a wood rasp for the drill finished off the hole. A wood chisel, the wood rasp and a coarse sanding disk were used to make a recess in the floor so the plate was truly flush. I placed the tiedowns on the long floor beams so the bolts just caught them. I used 7/16 grade 5 bolts instead of the usual 3/8 bolts for a little more strength without going to the expense of grade 8 bolts. I like it so far, flush fitting, looks decent and much more peace of mind tha the other ones LOL.
