First I agree with Rock, look for a used one.
The guy that sells Aspen used to work for Bunkhouse and their trailers are very similar but not completely alike, frame on the inside or outside is just one difference.
Bunkhouse makes the complete trailer at their factory.
Aspen buys the trailer from somebody else then puts their own "tent" on it.
I suggest you check out the trailer towing forum at this address (skip the advertisement popup)
Then I'll tell you my story, I did the research and bought a Bunkhouse,
I can honestly tell you it is a very well designed easy to put up and take down fantastic camper and so is the Aspen. (I had AC in mine)
Now for the rest of the story, I absolutely hated pulling that heavy ass thing with my LT.
Now if all you're going to do is run down the interstate, no problem.
But I don't like interstate, I ride on the backroads.
If somebody tells you they can't feel a 500 lb trailer behind their bike they're feeding you BS,
you need more stopping room and you have to slow down "before" you get into a corner or that trailer is going to push your rear end through it.
It scared the hell out of me in the rain.
We took ours from Florida to The UP of Michigan and back and after that I had had enough and sold it.
I replaced it with a Bushtec (much lighter)
