I once used an Isuzu TrooperII to tow a Westy from Ft. Lauderdale to Raleigh, using a tow bar.  I assume using an Xterra would be similar.

First, be VERY careful when you stop or the Vanagon will try to pass you!

Don't make any sudden moves.  I turned a corner too sharp coming out of a parking lot.  One of the van's tires rode up over a curb and both vehicles started rocking violently side to side (this was at only 5-10 MPH!)

I made the trip without any serious problems, but I'm sure it was hard on the Trooper.  I think I put some extra weight in the back of the Trooper to help stabilize things a bit.

Good luck, and take it slow!
