3 things.
1. I mistyped the date. This is 1992 Dalphin
2. The vehicle is running fine. Rocket science is not required.
3. I find nothing wrong with looking for baseline information.
I'm looking for a copy of an owner's manual for a '92 Dolphin. I'm willing to take and pay for a photocopy or scan to *.pdf. If I can fone the coach electrical that is good enough.
