I love my FWC Fleet. Bought it new in 2015 - not a shell, I got it built out. I'm glad I did.
I used it almost every weekend that first year, plus some longer week etc trips, and then lived in it and traveled for almost half a year. It lives on my truck 24/7. (daily commuter. yeah, I get worse gas mileage, but whatev. ha!)
"Is it worth the price" is a value perception. It's a lot of money to me, sure, but if I was a wealthy person, perhaps it wouldn't seem like much. And I've long thought I could just get a topper on my truck and a portable stove, etc... but this affords comfort and is pretty much hassle-free.
So it depends on what you think is worth your money
Is it worth your /time/ (which is valuable) to build a hardside and possibly save upfront money?
Or is it worth your now money to buy something done and solid?
Only you can answer those questions. From what I've seen on this forum, people love their pop-up campers and use them for many years. Also, if you are patient, you can probably find a good used one....
