I sold my 5th wheel and moved up to a motorhome so I no longer need this hitch.
Its a Pullrite 4100 Super Glide sliding hitch. Rated for 16000 lbs
It comes with the upgraded removable rails so they can be taken out when not being used. Also included is the capture plate and super rail kit that came off my 2011 Chevy 2500hd truck. The rail kit should fit 2011 Chevy trucks and newer
This hitch automatically slides when you turn your truck. No need to get out to pull any handles. Its all automatic. Here's a couple of you-tube videos explaining the hitch.
Brand new this set up would cost about $2000. I priced it to sell at $400
Thanks for looking
