I've been searching for an extended service contract that just covers the chassis rather than all the "house" items. It seems XtraRide has or had them but in talking to one of their dealers, he said they're not available. I can fix most anything that goes wrong above the chassis and can self insure for those items. If something significant goes wrong with the Cummins ISL or the Spartan chassis however it could run into some serious money. The dealer I bought my 2008 Dutch Star from wanted to sell me a gold plated contract from Cornerstone. Anyone know of a chassis only contract? Just trying to save some money here.
