If you have the $$$ and can stand the high dep. go for it, nothing like a new coach. Damon is now owned by Thor Industries I think, and you don't hear a lot of bad things about them. Whith that said all new coaches have shake down issues that will have to be delt with. Just check on your dealer, make sure they are as willing to take care of you warrenty issues, as they are to take your $$ for the sale.
If you look into the used market in todays world and no trade in, you should be able to make a good deal on a 3-5 year old used coach, and someone else has gone through the shakedown process. I have owned my 99 for 6 years with no more problems than friends with new coaches.
