I have a 2004 Monaco Cayman 36 PDD, and have no problems in getting into State or National Parks. I have upgraded the trailing arms to the Source Engineering arms, added Bilstein Shocks and enhanced the air bag system. Put in lcd televisions, get 10 to11 mpg. Turning radius is 50 degrees. I am actually upgrading and my Cayman will become on the market in the next 10 days.
