I was looking at house trucks and visited "sharky's" website and he now has a forum. Although not super active, very interesting.

I hope this does not upset the moderators here. This is not meant to replace the goodness that is this site, just suppliment it.
It's a bit of a throwback to the day's before the mass produced RV, when woodworking and craftmanship were appreciated. Somthing that seems to be lacking these days.
