Better idea, I had a friend that towed his cat behind the pop-up. He did that for years (just don't get where you have to back up!). You don't have to modify anything except adding a hitch to the camper. I would suggest putting brakes on the camper though to help in stopping a train wreck.

Only about 50% of the US states allow dual trailers (mostly states with strong agricultural industries).
I have seen that - a guy used to come to spring fever that way with an a-cat for a couple of years (back in 04-05). I looked at it myself but went the RV route instead. Now that I have an a-cat and it's so portable, I'm thinking about putting A/C in the back of my pickup truck (under the shell) and sleeping back there.
