Heads up on several issues specific to vintage Trilliums...
. They are screwed to wood strips inside the shell. Many have rotted wood due to neglected leaks
. Ask the seller when they last sealed the windows
and whether they replaced the wood strips. If you arenít confident in their answer, assume you will be doing this repair.
(2) Belly band. All Trilliums eventually leak through the belly band. I donít recall all the details of the fix, but it takes some fiberglass work and a fair bit of time. Excessive caulk around the belly band trim is a warning sign. Again, find out if itís been done already.
(3) Floor. The fiberglass floor has a wood core. If water gets in (cracks, screws, plumbing penetrations...) the wood can rot. Repair is a bear. If the floor feels spongy, pass.
(4) Frame. The weak spot is where the frame curves upward at the front of the cabin. Look for cracks (bad) or a proper fishplate reinforcement (good). A questionable frame can be refurbished, but youíll have to separate the shell from the frame.
(5) Sag. My memory is a little fuzzy on this, but some units develop a sag in the front curbside corner forward of the door. No known fix.
Three other things are worth mentioning. First, the door has a molded strip that doesnít quite align with the belly band near the door handle. Itís normal, caused by a molding error. Second, the bolts that hold the shell to the frame rust out over time. More than a few people have discovered their trailers are holding together mainly by gravity and friction. Replacement is not a big deal, but itís something to check right away. For some itís an opportunity to lift the shell off and refurbish the frame.
Third, and this affects many older molded trailers, rubber torsion axles have a working life of 15-20 years but can roll on well past with decreasing ride quality. Try to find out if and when the axle
was last replaced. One simple test is to jack up one side of the trailer on the frame near the axle
and see how much the wheel drops as the frame sides. Little or no movement means an aged out axle
. Figure $800 or so for replacement including labor.
