Will This Be a Bad Move for a New RVer?

I doubt a vendor at a air show will not have plenty of space. I recommend buying more used RV than you think you need...ONE TIME as trading will be expensive, BUT I doubt you need something that big or new. A longer trailer is easier to back up than a short one so other than a 5er wanting to cut the corner in a turn, not that much difference.

I would think something like this would do and I see a lot of Raptors. I would still go with a serious truck.

Something other than "Spring" would help on your location.
