Thanks for the advice, especially agefhx! I'll definately remember that.
MT, when I'm ready to upgrade, I'll be sure to let you know.
As for WHY, I'm looking for a new project vehicle. My Ford Explorer is a bit cramped, the last server I installed took up precious space, and the wiring was a bit tricky. I look forward to doing things like data acquisition on all the sensors, putting in a couple LCD monitors, MP3 server, etc. My wife is going to have fun using it as her own project too, re-decorating, etc.
The main reason, of course, is that I want to spend more time with my family. I work long hours, and on the weekends, we often find ourselves glued to the TV. If we had an RV (we reasoned), we could take off to places a few hours away and spend more time together doing things like seeing interesting places without being too far from 'home'.
Plus, my wife misses her family up north (we live in LA, but we both came from Eugene, OR). She drives up occasionally, but the 16-20 hour drive is pretty tough with a 1 year old in a car seat and she doesn't like sleeping on her parents couch, so.... the RV seems to be the ideal solution. The reduced mileage means that it costs about as much as driving up and staying in a motel along the way, but it's much more comfortable. Plus, she'll have a place to herself when she's in Eugene or Seattle (the other place we visit).
BTW, Midnight Target, that's one cool trailer!
