I am planning on downsizing my class A to a B+ rv under 25 foot, was also looking at new trucks and a camper as a 2nd option, so with the price of a new F-250 to F-350 and a new camper with a slideout...
There are some new B's featured in the "2021 Hot Products" section of RV Business, and going for $150k+ built on a Benz sprinter platform. I remember looking at TCs at the Hershey show when we were shopping for the Terry and was amazed at the prices...$50-60K for a TC when our 34' Terry fully loaded was $32k....and a TC doesn't even have axles or any kind of running gear!
After re-building our Lance, I would say they're built better than the average TT though.
