Hi - you're welcome to visit the New England Unit site here; http://newengland.wbcci.net
If there are rallies close enough to you, you could come out and meet folks and see some trailers. There's one coming up (not NEU sponsored) in a beautiful site in Bristol, VT the last weekend in Sept (see pic below).
I think the closest dealer to you is Airstream of New England in Stoughton, MA if you want to check out some aluminum that way.
Hope those are some good places to start!
