I'm actually considering having a 2" hitch receiver welded to the bottom of my rear AS bumper. Not to tow anything, only to insert 2" hitch receiver compatible accessories including my 2" hitch receiver bike rack. Normally it sits in my TV hitch receiver, but I figure I can shift my four bike rack to the AS-installed hitch receiver when I go on the road. The RV place that will do this for me says carrying 300 lbs. in bikes won't be a problem, although the install isn't cheap but it's less than the AS solution.
That and there's a wide variety of cool accessories that fit the hitch receiver, such as grills. My personal favorite accessory is this handy item for boon-docking:
Off-Road Commode, Model# ORC | Hitch Accessories| Northern Tool + Equipment
This makes a great AS gift, btw. No pun intended. ;-)
