We are getting pretty close to pulling the trigger for late fall delivery, likely on the 2013 Ram 3500 diesel crew cab chassis.
We've been looking for a small motor home for a while, and the ability to go off-road is a big plus. Hard to find little ones in the US -- we've rented similar vehicles in Oz, NZ, and Europe though. The van types don't quite do it for us.
