Before I purchased my '96 I did a lot of research on Sprinter vans and 4x4. The '05 and '06 years seemed to be recommended for several reasons dealing with simpler engines. There are always one or two for sale on ebay for around $40,000, usually the Itasca or Minnie Winnie versions or straight up van conversions. These guys in CA have been doing the 4x4 conversions for a long time and convert used Sprinters to 4x4:

Problem is the the total cost was always double what the Airstream was going to be and although the gas mileage in the Sprinter is much better, it would take far more miles than I would drive to make up the difference. AND, I really like the high ceiling in our Airstreams--they are really liveable. Also, there have been millions of Econoline vans sold in the usa and while the sprinter has been in Europe for decades, if you are not working for FedEx, it is not always so easy finding a shop to get them worked on... Chrysler, now Chrylser/Fiat, is pushing the Fiat based vans and is no longer selling Sprinter vans = if you live in a rural area, as I do, makes it harder still. There is a Ford dealer right in town and easy to get them worked on everywhere. Having said all that, if I was not worried about 4x4, a used sprinter is a really appealing option given how nicely they handle. AND, the new ones are coming with a 4x4 option and if you let Sportsmobile do its thing, all can be yours for $120K. Now, if only my Powerball# would come through...
