Quote from: MountainDon on March 21, 2023, 02:38:48 PMSo this is an enclosed trailer, sorta like a cargo trailer but built on a gooseneck chassis? If so, ask the constructor how to best safely attach to the shell structure he builds.
If you mean you want to take a flat deck equipment gooseneck trailer and build a house structure on it yourself I personally would rethink that whole idea. I believe the weight would get very heavy if the entire shell was built from wood. Plus welded steel tubing is better suited to a mobile structure. (or aluminum tubing if done by a certified aluminum welder.)
Perhaps I don't fully understand the purpose and what/how you wish to do this?
