That's one all around fine rig didn't anybody tell you different. Lots of proven bullet proof in it. The build sheet should have the ser # of engine as well as many other items. Mine is in bedroom cabinet. If you have all books/binders from Monaco that year there should be a lot of info, maybe no service records . But I have all grease points ,filter #s,oil types and capacities , paint codes.I hope you got everything. Mine has wiring diagrams thank god, I could live without everything else. Even had every sony warranty card lol. Need a Trinatron manual I had it, every speaker, amp ,radio.
Get some test strips "just a few check exp. dates" for SCA in coolant I did before purchase very important as not to erode wet cylinder sleeves . Change the oil and filter save a sample. Get all fluids tested . Try to find out if tranny was upgraded to Transyn fluid. I had sticker for that PO promised me he had it change a second time as well. You should never have to change if it is just test. There is supposed way to register your cummins ser# with them get all sort of info IDK haven't done it as of yet.
