As an alternative, if you are going toadless, I've seen some small trailers that are offices. I wonder if one can get one with the total weight under 5000 pounds.
The idea comes from some people I know who hit a renaissance faire. They have a diesel pusher, and a fairly large trailer behind it. When they set up camp, the sedan and motorcycle are pulled out from the trailer. The trailer then becomes their office. Of course, one can't pull that much with a Winnebago View, but it might be the case that a small trailer can double as office space.
