There are vans all over Thailand like that. I think they are great. I guess you'd scale down and use all the gas $$ saved to rent a motel room now and then?
In our B we do that anyway. Just because you take your bed with you, doesn't
exclude you from a little self-indulgence at a nice motel/hotel once in a while.
The Delica looks like it would be rugged and fun, with the crash bars and all!!! :supz:
