Transitioning Class A to Super duty truck and Fifth Wheel

I looked at both floorplans which are very similar. Only difference I could see was that the Cougar had optional fold out bed/theater seating. The GD also does not have the heating ducts in the floors - really nice as they dont collect dirt. As an owner of a GD product, I've had a great experience with their service - before and after warranty period. Take a look at the GD Owners Forum where you can find more info on the 260RD - and people are generally friendlier.
