Hi Everyone! New Trillium owner

Hi All.. My Names Dave So I just purchased a new (old..lol) Trillium trailer.. Greenish gelcoat 1975. Just finished changing the weeny 185-80 13 tires to better 205 75 R14,.. Much nicer...
Have a few issues- lots of wiring to do and reglue of the insulation in one corner (old leak there)... and revamp the interior and replace the doors etc..
Main door hinge screws are stripped so thats another bit of trickery .. cant see whats behind the screws?. or get at it due to the insulation- any ideas?..

Welcome David!

There are four items on a classic Trillium that have to be addressed, eventually.

The door needs to be reinstalled:
There are a number of approaches to this, but the one that makes the most sense to me is to peel back the insulation, known as Ensolite. Then, cut into the fibreglass under the Ensolite, where the hinges are. Then install stainless steel backing plates that are drilled to match the hinge. Using stainless, countersunk screws, and lock nuts, to remount the door. Some put covers over the holes, others re-glass the holes and re-glue the Ensolite.

The windows have to be resealed.
Take out the screws, (many will have rusted through). Pull the window out from the bottom. Then scrape off the old butyl putty. Put on new butyl putty, (3/4" wide).
If you are lucky, the wood that the windows screw into will not be rotten, but odds are that at least one of the windows will have rotten wood. The hard part of replacing the wood is getting the Ensolite off. The glue that Trillium used is some sticky stuff. I have found that a sharp putty knife helps. Then using new, preferably stainless screws, reinstall the windows.
My first Trillium window thread.

The belly band has to be sealed:
This one is quite involved.

The axle should be replaced:
After 40 years, or so, the axle is done. Get brakes on the replacement.
