"It's what Toy Haulers were designed to do"...
Usually at a huge sacrifice to the creature comforts in the non-garage portion of the rig. Lots of folks have used the single wheel or the dual wheel swivel wheel trailer. We don't like ours to be in the open, subject to road grime, rain etc., and prying eyes...we prefer an enclosed, nondescript cargo trailer....but we use 2 trucks to facilitate our travel.
The general consensus is that the frame on a DRV is stout enough to handle a Harley loader.
"Hmmmmm New Horizons start at, yes start at $100K"...
Same with DRV's but there is nothing wrong with looking for used units.
