Welcome aboard. I think you are going to like Airstreaming a lot. Take your time looking for a trailer and don't just "settle" because it is cheap or close by or... There are lots of really bright folks on this forum (I'm not one of them but I have stayed in a Holiday Inn Express!) and their collective wisdom is very helpful.
As for tow vehicles -- that is a never-ending debate hereabouts -- I tow with a Nissan Titan, a half-ton pickup, and I am pulling a 31' Sovereign
. Have had no problems so far. Wouldn't enter the Pike's Peak Climb but....
Towing equipment is another never-ending debate (as it should be). Some wil never set out without $3k worth of Hensley Hitch and others swear they can tow with a Wal-Mart bumper hitch. All I can say is read, read, read the posts and ponder... If you can, you might mosey by a WBCCI or AIR rally and talk to real, live people (that's what we did).
Again, welcome aboard.
