I had to think twice about an extended warranty yesterday while sitting at the Cummins dealer getting some preventative maintenance done on our DP. We were there for a simple fluids change, but there was another couple of who had been there going on a week...for a new fuel pump. Now granted, I don't know the extent of their story, or what else was wrong, but the gentlemen indicated that the total bill for the pump and labor was going to be around $6k. Like I said, I don't know what this all included, but he alluded to it being just related to the fuel pump on his DP...so that got me really thinking twice about an extended warranty...is it worth it or not, I don't know, but if it would have covered any of his $6k bill, it surely would have been worth the effort into looking at the coverage.
