My same answer on other post applies to this one the Spartan is the only DP chassis Newmar uses an its a good one. I'am partial to the KS because of price and most of the same options as DP'S lower costs for gas and with the newer 25,500 WH coming out in 06 I would stay with gas.
The ride on DP would only sway me if I could aford one. But its fun anyhow looking at all the options out there ,so have fun and good luck in your desision.
