I sighted this Camel Trophy rig out in UT last week. A couple from England wandering the US for 5 months! (Oh, to have a strong currency...) Pretty neat, I admit.
That's a mighty nice Land Rover Defender. Those Camel Trophy videos are a blast to watch.
The roof top tents are cool, but I think some owners are starting to figure out that they still don't give you a place to get out of the weather or a place to change.
