We had a friend sell their used pup in about 30 minutes from the time they put the sign on. They may be a dying breed but still in major demand. I know they are now few and far between, but I’ll take my pup any day. TT’s are just traveling apartments. When you sit in the pup you have window views 360. We upgraded a few years ago to a higher end pup and love it. It has motorized roof and sleeps more than a tt that’s 10’ bigger.
