Well, the 1-ton dually truck you need to pull that rig is just plain big. Long, probably 20-21 ft, and wide at the rear wheels. Truck lovers probably think that's a plus, but in my opinion its a minor nuisance at the grocery store, shopping mall, and many restaurant parking spots. As far as driving it, though, it rides and handles well and certainly comfortable and reasonably quiet. Unless you get a bare bones model it will have all the creature comforts of a nice sedan.
Realistically, you have no choice but to get the one-ton (or larger) truck if you want that nice 5W. The only alternative is a motorhome and pull a smaller toad.
