Hi, I know this subject has had a lot of information, but I do have a question that I want to verify. i am looking at a 2002 Monaco Knight that is several hundred miles away. . According to the sales brochure, it has a RM4C chassis. I have found no reference to this chassis code. is it possible this coach would have been built before the R4R or RR4R? I hate to drive several hundred miles to crawl underneath, and the seller is too old to crawl under. Thanks.. p.s. I have had 2 previous Monaco pushers.
