Welcome to the Newmar forum & irv2 mindilew.
Congrats on your DS many safe miles of enjoyment for you.
Here is a gas
Owners Guide for DS, here is
one for DP.
Here is a
brochure for that year.
Here is a link as to how your coach was built.
You may find not much difference between Owners Guides and if they have them at end of guide there will be some wiring & plumbing diagrams that are only general to say the least DP GUIDES will have better wiring & plumbing diagrams.
The brochure will have weight and tank sizes plus other information.
We are here for more questions so do ask.
