B&W Companion 5th Wheel Hitch W/slider base - $1,399 (KNOXVILLE)

B&W Companion 5th Wheel Trailer Hitch w/ Slider - Dual Jaw - 20,000 lbs capacity.
I am looking for either an even $0 trade with a B&W companion with a non-sliding base in the same condition, or a right-out buy for cash.
I've only used mine a handful of times, so only minor marks on the top surface.
I purchase this model thinking my truck would need the extra clearance, but I have NOT had a need for the extra adjustment.
I purchased this new last spring for $1700.
Serious inquiries only please.
