I have one foot in the other camp as well and one in the TC camp. We just bought a 2011 Airstream Avenue for my photo adventures and some spur of the moment camping trips or road trips in the SW. I am currently having it lifted and 33" tires put on it so it is more user friendly on the back roads and two track roads, plan on keeping it 2 wheel drive, right now anyways. We will keep the TC because it's like a mansion now, compared to the van. Have fun with your Transit, I think it will make a good base for your conversion!
