We've had our '05 40KD since July and we can't wait to get in it every week. So far we're only weekenders. We've had numerous teenaged guests and they seem to like it. I thought we kicked the kids out long ago..... The ride is very smooth and the diesel is a sweet hummer. Our mileage is 6-9 mpg depending on if I or my wife drives. Of course I get the better gas mileage. I can't get my wife out of the captain's chair. She does most of the driving. It's very easy. We really like the basement air. It's very quiet in the living room. A little noisy in the bedroom, but no than a roof mounted unit.
It does great dry camping as well. Good luck and congratulations.
We have the 2003 identical coach. It is our frist MH and we have enjoyed it. It is easy to drive and park. You can stay in almost any park with room to spare. I like the large CCC and the 10k hitch. The 300hp cummings 5.9l and 6 speed Allison 3000MH combination is very reliable and we get 9-10mpg. We are thinking of remodeling ,replacing the sofa with a euro chair and table. We hope you enjoy your new coach!
Have a 02 40ftQD horizon. have put 47k miles on so far. Have done all of Canada, 40 0f the 50 states, starting to repeat some of the States. Love every mile, very satisfied with it. Minor problems have been taken care of, good luck with your new one.
