I am a new owner of a 1989 coachmen 31’ motorhome. I am trying to identify the drivetrain. I have contacted Forest River and they did respond back but said they had no records to be able to assist.
This RV has a 454 gas engine which tells me it’s a General Motors drivetrain. The title lists the RV as a 1989 but my understanding is that GM went from carburetors to fuel injection in 1988 for the 454. I assume Coachmen used a dated drivetrain and titled it for the year they completed it?
Also found that the chassis could possibly be either a 3500HD or a P30? Would like to determine what the correct identification would be when buying replacement parts.

Thanks
Warren
