So, IMHO from experience, prices on PUP's are way too high. A family of 4 can buy a TT for MUCH LESS. Add that to all the new 'lightweight' TT's on the market and you can see why so many campers are switching to a small TT instead of a PUP.
That's why I think there are so few PUP's on the road nowadays. It's less expensive to buy a TT, AND they have a whole lot more room for less $$.
That's what I ended doing I bought one of those lightweight TT's with a slide and it cost less than a used PU. Hard to justify buying a new PUP that costs more than a nice TT.
I am surprised that more PUP manufactures haven't gone out of business or dropped their PU lines.
Boy, would this start an argument on Popup Portal! LOL
To many, it's camping in a box vs. feeling and hearing the sounds of the outdoors.
Price-wise, I've seen the BEST highwall (Rockwood HW296) go for $15,500 new. Aren't most new TTs that much or more? I personally paid $9,500 for my 2012 Clipper 126.
Mileage is also significantly better with a pup, and you don't need a full-blown truck as the heaviest non-highwall trailers are less than 3,000 lbs. dry. Ever see a WDH on a pup?
Some enjoy camping with all the conveniences of home. We have never even put water in the water tank of either of our trailers (since 2006) and are usually outside the trailer, even in winter. A lot of pup owners are the same or similar.
This all being said, the natural progression as popup campers get older seems to be sell the pup and get an HTT or TT because they are easier to set up. That's what we are planning to do.
I am still shocked by how big some TTs and fivers are. It was one of the many pleasant surprises of our first trip back to the states in ten years.
