I just towed my new (new to me) Vanagon home last weekend.  I used a
towbar & a 94 (yes I'm ashamed--it wasn't mine) Ford Thunderbird.  The
only problem I had was the towbar used chains to hookup underneath to the
frame.  The washer fuild resevoir was in the way and had to be removed.
Another than that, I towed it about 100 kms no problems.  It was actually
lighter behind the T-bird than I had expected.   I bet it was the only
time my van will get to go over 70 mph!!
