Lighter Trillium?

[Roy in TO]

Some of the weights are "hidden". Under the cushions are particle board "storage hatch" covers that could be replaced with lighter materials. The dining table is incredibly heavy and could be replaced with something lighter.

As for replacing 2 20 Lb tanks with 2 10's or 5's ... remember that a single tank weighs less than 2 smaller ones.

Like others have said, go through what you carry. The first few years while we were restoring we were constantly removing tools and repair materials in and out of the trailer and packing up gear in a hodge podge. We finally got to the point where we could sort our gear and pack the trailer once and for all. We soon discovered we had duplicates of many things we really didn't need. Most memorable was realizing that we had been carrying around 5 egg flippers in our little egg.

I was thinking maybe sub some of the steel frame with aluminum or something.

Steel and aluminum do not mix well, so it needs to be all steel or all aluminum.
A member here used to own an 1980something 13' Burro that was manufactured with an aluminum frame. It was weak at the bend where the tongue begins, and cracked there. After it was repaired and reinforced, the next owner experienced having the tongue break completely off!
