I still have a lot to figure out on my own- wall construction style, design/shape, skin, trim and finish, etc. First things first, though, I'll be moving forward on building the trailer. Most likely, this will be from scratch and will be welded frame. I'm pretty sure I'll be going the 5x8 route. I'm a pretty tall guy, so the more room, the better.
With a very wide variety of experience (ranging from aircraft overhaul, light construction framing, plumbing, home and automotive electrical, and all the way up to communication tower, overhead power line, and substation engineering and construction), I think I'll be able to pull off a decent homemade job. I truly will have to be careful to avoid over-building the TD, though. It should be said that I lack any sort of skill in finish carpentry, however. This element will definitely be a HUGE learning experience for me. Thankfully, one of the guys I work with has a side business of cabinet making, complete with CNC setup and all. I'll try to beg help from him, if it gets down to it, but hopefully I can limit it to having him fabricate the cabinet faces and doors for me. He's not cheap, and I really need to be cheap on this build.
The plan is to have this TD be the roving home for my little miniature Australian Shepherd and I on little treks across the western U.S. We plan on taking small 3-day trips, maybe a day or two longer here and there. For the big family trips, the Class A diesel pusher will win out, and the TD will have to stay home.

Anyway, thanks for having me as part of your community. I very much look forward to journaling the build here and meeting some of you one day!
