1979 Trillium roof support

Hi there,

I am looking to remove hacked together yet structural "furniture" from my trailer and make new ones. I am looking for ideas for low profile ceiling bracing that would give me lightweight structural support. Any ideas would be much appreciated.

Post pictures indicating the portion of the roof needing support, and what is below this part of the roof now.

Hello John,

Thank you again for your reply. Have a look at the attached photo. I would like to make a full size bed and possibly get rid of the closet at the entrance. I would like to make some low profile roof support to do so...

Seems clear you already know the cabinets are a main roof support. If you're only looking to add the few inches to allow for the width of a double bed you might just cut each cabinet down accordingly, leaving the rest in place

I have seen numerous floor-to-ceiling roof braces, basically a partition or wall, cut from plywood. Another option would be to insert one or more posts.

Closet is the main support for that wall and the door jamb. I wouldn't touch it.

If you really want a large bed, I'd sell your Trillium and get something else. There are other brands with more spacious bed area.

All the fiberglass cabinets are structural, not just for the roof.

Thank you very much for the comment. Yes, I understand the idea of support. The cabinet however moves freely and its role as a support is somewhat limited as it stands.

Additionally, I have a bit of a sag in the center of the roof where the cutout for the fan is. I would like to build a solid (yet ultra light) cabinet that would extend all the way up to the higher portion of the roof and give support to the center part of the roof. Does that make sense?

So what model Trillium do you have? There are lots of differences. If your cabinets are wood, you have more choices. On the 1300 and 4500 models, the original cabinets were fiberglassed to the shell and floor.

Hello Bill, yes, my cabinets are all wood.

If you go to this site, you can see how this boler was modified. https://www.proud-canadian.com/13-bo...eyond-1/boler/


I have seen a number of people make an interior arch that they then turn into a "room" divider.



Could not find the picture I am looking for, but it is on this site somewhere.



Hope this helps

Thank you very much, yes, this is a very interesting solution - exactly what I have been looking for. I am sure those supports could be extended to address the center of the roof sagging area.
