We went from a 5er/toyhauler to a TC and a toad. We were using the truck as our "get around vehicle" when we had the 5er. Of course at the time, the truck we had was a 3/4 ton short bed and not a dually, making it easier to park.
We switched from the 5er to the TC as we had changed where we were going and what we were doing when we were camping. We spend very little time inside the TC.
Keep one important thing in mind - you are going to give up a LOT of storage space, elbow room and floor space when you switch. I see "fulltimer" in your signature. I would do some SERIOUS thinking and research before I would make the switch. If you are stuck inside for an extended period of time you will get cabin fever very quickly. Even with the slide on our TC, if DW and I are both moving around we are rubbing against each other. (not that there is anything wrong with that.)
Maybe you should think about a toyhauler and a SmartCar? Not trying to discourage you - just dont want you to spend lots of $$$ then later say "we made a bad decision!"
