I see they are offering sprinter conversions. The short body ones look
to be around 48K and up. When you consider all your getting plus the
21mpg it's something to think about. That said I don't have any
experience driving a sprinter or other bigger vans. I've heard it's
very different. I guess it's a little give and take and depends a lot
on how and where you use it.

I saw Dennis H new BIG, BIG camper, truck, bus thing and man is that
thing cool! but it's made for a different kind of taveling.
