This is actually a model 3155RL Keystone Montana, but Rvtrader does not let that trim to be chosen when posting this listing.  Keystone Montana is the best selling fifth wheel brand in America and one of the most recognized names in fifth wheels. 

This is a great one owner camper in excellent condition that has seen minimal use.  The camper has been shedded when not in use.  One great feature is the Outdoor entertainment center with awning.     
  
Other Features:
6 point Hydraulic auto leveling system
Fireplace
Upgraded leather theatre seats.  (original matching recliners are available)
16" aluminum wheels.

The youtube video link does a great job of describing this fifthwheel.
