The exhaust is the real catcher. You would either have to bridge under it (weakening the hitch) or redirect he exhaust (in my view unacceptable).
The wife and I had discussed it, a while back, there is plenty of room in the truck for luggage for even a week or so, but if you add gifts or other non-essentials it can be a real hastle. And, we were thinking one of those little untra-light motorcycle trailers wouldn't be too bad, they have some nice striking designs, and wouldn't be hard to find one that didn't clash and might even compliment with the shape of the car, then we would just have pay that bloated cost for the SSB paint.
So far we are getting around it with simplifying. And, driving a half a suit of armour this last holiday. :wink:
