In reply to SKJSS (formerly Klayfish) :
Then it looks like maybe motorhome with a toad. For the size TT you're thinking, you need a LOT of SUV. I personally wouldn't even think about something over 32' without a dually, or at least a 1-ton SRW with some upgrades. The longer the TT, the longer your wheelbase will need to be as well. You're talking about a truck that might sit for 80% of the year unless you can deal with DDing a long, fat commuter that sucks fuel. At least with a class A, it will also sit for 80% of the year and also sucks fuel, but you know that going into it.
The downside is additional maintenance, registration, and insurance with a class A, PLUS the maintenance, registration, and insurance on a toad. At least when a TT is sitting idle, it's not costing you as much money and effort.
Do the math for your state. Here in PA, trailers don't need to be insured. They're covered by the liability limits of the tow vehicle. If you want, you could of course add comp/collision to a trailer to protect your investment. Registration for a trailer is about $32/yr, whereas a class A would likely be a class 3 or 4 which is around $300/yr. Insuring a class A is a crap shoot. Could be cheap, could be expensive.
In my world, I tow a lot, so it makes sense for me to DD a full size van. If you don't have the need to tow, it might not make sense to have a big tow pig.
That was a lot of rambling, but put it this way... either way (these are true regardless of TT/SUV or Class A/toad) you'll have a large, fuel-sucking vehicle that rarely gets used, plus something to tow behind it. In the case of the class A/toad, you have two motor vehicles and the expenses that go with it. In the case of the SUV/TT, you'll have one motor vehicle, and one towable.
Is it possible to re-think the length of the RV? 35' is massive. A 30' or 26' could be towed with a MUCH broader selection of vehicles that don't have 6 tires.
