I have a 2013 Jayco Caravan and Pop Top brochure in pdf in my file, gives good detail on layouts if thats any help................ the manuals are usually pretty ordinary and not really manuals at all.... The best thing to do is to get the model number of the fridge, AC, HWS and download the manuals for them ....
Here's a link to a good selection of How To's;
While digging in my HDD also found "Trevor Eastmans Camper care Manual" this little gem for Jayco campers is very good for those with windups, covers all the stuff ................... sadly its too big to attach even as a zip so will see how I can modify it..... I had forgotten all about it ....
