Expedition Portal forum has a sub forum just for vans. Some cool stuff there. I like the shorter vans better than the extended vans personally to keep the departure angle down. Diesel is nice but our v10 seems to be working just fine. You will need a small trailer for the SxS. If you find a good deal on a 2wd, don't rule that out. There's a guy in Santee that makes a badass 4x4 conversion IFS and is way better than the straight axle setups from SM, Quigley and Quadvan. They stopped making the E350 this year so they are becoming hard to find new and used ones are getting bought up as well.
