Sorry I dropped off the face of the earth like that. That applied to my entire life, not just you.
A lot has changed, I don't want to go into detail but I'm on short-term disability now so I have rather more time and less money, and home building is out of the question for the moment but hopefully that can be reconsidered in a couple years. However, I only mention this to explain how things have changed since my prior intro. I want to talk about teardrops and camping here, not about my troubles.
So, responses to your comments above, even though you made them long long ago:
I know it's possible to build light with plywood, but I happen to be overly fond of snazzy materials. To put it in perspective, I was seriously considering having a transparent polycarbonate hardtop custom built for my Miata, as I consider it a vast oversight that no one seems to make such a thing. Of course, at the moment that's academic, but still.
I need my eventual trailer to sleep two adults comfortably and three if they're real cozy, so I'm thinking a 5x8 - and with A/C, since that's a lot of body heat in a small space.
I did actually say I was looking to buy something soon and build what I really want later... but the design and build are so much more exciting, it's no wonder everyone's latched onto that

QuietOutdoorsman, the just-finished 20-story tower in downtown Bellevue where they had the horrible crane accident is my company's new office. How's that for an omen?
Cliffmeister2000, by integrated WiFi I mean to build a long antenna into the frame to support 802.11 as well as cell network internet. Campgrounds are certainly moving toward offering it: http://www.dslreports.com/shownews/WiFi ... -You-93544
Of course, I also intend to spend some time away from such vestiges of civilization as cell service or designated pooping huts. Which leads to another design requirement: the trailer has to be able to make it down Forest Service "roads" that may or may not have deserved the appellation before the last few winters' storms. Plus we have to be able to unhook it in somewhat adverse conditions when we decide the car really can't make it any farther, and we need to turn around on a mountainside track that was only 1.5 cars wide in mint condition, before it washed out. Mind you, we are talking about keeping up with a passenger vehicle, not a 4x4, so it probably just needs some extra clearance and a little attention paid to shock resistance.
My Miata's already not under warranty, so no worries there.
Greg M, I'll fight you for the geek title - my laptop can beat up your laptop, nyaaah!
