Many of the cabinet and interior items are the same, especially if you are talking about manufacturers who make both Class A and TT's. Just like there are various levels of TT, there are also high end and low end motor homes.
What you are trying to do is compare apples to oranges and you just can't do that with RV's.
I've watched many TT owners setting up their rigs and I see how long it takes, especially in the rain. I can pull in to a parking space, and while still in the driver's seat I can level the coach. Then without going outside in the rain I can extend the slides, put up the satellite dish or antenna and watch TV while fixing dinner in the microwave or stove without having to fire up the generator.
When it comes time to leave, I pull in the slides, raise the levelers, lower the antennas, and I'm on my way, without ever having to get wet or muddy outside.
