Chassis size

We have a 1985 GMC Coachmen, class A, 454 cu.in. When we ask for parts at the auto parts store, we get told that they can't look up motorhomes. They keep asking if it is a 1500, 2500, or 3500. Our motorhome is 24 foot long. How do we find out what the size is? Thank you in advance for your help.

It would be more than likely a P30 chassis and you could use 3500 for motor stuff

Your motor is older than the parts guy and he only speaks liters. He has no idea what a 454 is or even if it is a chevy motor. Your motorhome is a P30 GM chassis. Their computer will know what that is. That chassis has been used in millions of commercial truck and motorhome applications. Napa will have your parts. The auto stores that sell air fresheners and blue fender well lights won't have a clue.

Good advice. Also, someone elsewhere said "ask the oldest person in the store"

Red face Many Thanks

Thank you very much to those that responded!! It is very much appreciated! Another question: Can anyone tell me if this size would apply to the brakes as well?

The best place to ask questions about your chassis is the Workhorse and Chevrolet forum.

Workhorse and Chevrolet Chassis Motorhome Forum - iRV2 Forums

If you need help with the motorhome (house) itself try the Vintage RV forum.

A "P30" is NOT at all the same as a 3500. Similar, to be sure, and engine internal parts are probably the same, but alternators, starters, belts, hoses, radiators, brakes, steering, suspension, etc. are all highly likely to be different. In other words, anything you are likely to be asking for in an auto parts store is probably different.

P30 and have them check GMC and Chevy if the part is not showing. On my previous RV (1992 P30) I used Chevy most often but found stuff via GMC at times. Also if it says all except motorhome chassis take it with a grain of salt and compare the part.
