GDeen, we are currently Airstreaming in the new to us 1984 279 motorhome without towed. the LX is a bit too heavy for the airstream/P-30 chevy chassis to tow. We are looking at a 2004 Wrangler Rubicon for that coach.
The bus pulls the LX without trouble. We put the LX into tranny neutral, then transfer neutral, then turn engine off, place transmission into PARK, and make sure key, better to use the valet key, is in place turned all the way counter clockwise like you are going to pull it out but DON'T. Your set!
We use a BlueOx Baseplate, installed ourselves, 4 bolts, and ran a wire from the baseplate plug to a T-Bar light bar that goes inot the hitch reciever and we are off. Towed the LX now for 7,700 miles without incident.
BlueOx makes a base for the GX too
