I started looking at a class b RV back in 05 but felt the SMB was fine size wise. After I found out where I can go with my Ford 4x4 SMB I was so glad I moved away from the larger RV. But it sure is nice having more room especially if you're full timing. New vs old? You can spec out a new vehicle but it will cost you. Also the Ford SMB's are now built off the cutaway body however the newer Sprinter 4x4 is worth a close look as well.
I like being able to go pretty much anywhere. Much to the chagrin of my fiance, we end up driving many trails just to see where they go. Losing the freedom to do this was one of my bigger concerns in going with a Transit or Sprinter.
On the other hand, I'll be hauling dirtbikes around a decent amount as well. And the slightly more space in the Transit seems like it would be pretty useful.
