Welcome, nice looking little rig there. Make sure to post up some pictures! We likes pictures.
What owner's manuals exist are extremely generic. Make a list of all your appliances with model numbers and serial numbers then hit up the www for the appropriate manuals. Some of them are on the Dutchmen site, many will be on the individual manufacturers' sites.
If you hit something that doesn't jibe or can't figure out, come around and ask. We are a friendly bunch and enjoy problem solving. There is a massive amount of RV experience on the board here and if someone hasn't seen it before they may have seen something similar.
Interesting side note... I was in San Antonio last week for work.
I have a couple of crews at the Frito-Lay there.
