This is a very nice, well designed and well built 5th wheel. With the upgraded windows and additional insulation it is the quietest 5 wheel we have ever been in. We use 1/10 the propane. The Disc Brakes and Gooseneck Hitch bring a whole new perspective to towing a 5th wheel. While it is an excellent RV to tow it is very spacious and comfortable. 


The only reason we are selling is due to health reasons. To my knowledge there isn't Anything wrong with this camper and you can’t say that when you buy a new camper. 

OUR CAMPER IS LOCATED IN NORTH JACKSONVILLE FL.
