It sounds like the OP wants TT features in a PUP.
As Manualman pointed out camping in a PUP and RVing in a TT are not the same.
You can get a lot of almost equal features in a PUP or you can look for a used Hi-LO or Trailmaner. But, you start approaching the price of a TT rather quickly.
The DW and I could not make up our mind which way to go so we rented the size TT we thought we would want for a week and drove to the Ozarks. Learned a lot very quickly.
I still have the PUP because it has sleeping space for all the grandkids and I like the camping feel of it. However, the majority of our siteseeing travel is with the TT.
