Some good information regarding the P30 chassis do some research as to what you for sure have. P30 is a generic term for the chassis but their were several versions and ording p30 stuff when you a p32 or a p42 will probably end up with you getting incorrect parts. You have already known that,maybe not. I've got 2 chassis motorhomes so I learn what I have to https://www.oemys-performance.com/media/p32-chassis-alignment.pdf#:~:text=Chevrolet had 7 model numbers for the,the alignment specs for the truck version.
I've been doing plenty of that. But I think I might have a PDF file that explains the chassis issue. I'll post a picture from the manual that trys to give correct identification info.

Welcome, does it have the 19.5 wheels? I've been looking for an 8 lug set for a few years,
Nope, not yet. Tires and Wheels website has them though. If you're not looking for anything fancy, check out the JANTSA steel wheels. Steel, dually compatible, 8 on 6.5 in Chevy/Dodge/Ford hubs, rated at 4000-5000lbs per rim, and not a bad price. Trying to save up enough to get all 7 at once. The shipping is going to be the bear on that though.

Hey, Ali. Where you at in Austria? I'm currently here myself. Vienna, on my way up the river towards Germany.
I'm in Graz, in the south of Styria. Are you on a Danube river cruise?
Enjoy your stay and have a great trip.

No, this is the original P30 chassis with the 8 on 6.5 lug pattern. The 'Workhorse' chassis came out about '88-'89 model year. They did produce the 10 lug precursor with the 178 inch frame, but mine is the 158 inch frame for this year, but most of those were in the 33-35 ft class of motorhomes. Mine is considered as 27ft even though it measures 28' 9' bumper to bumper.
Welcome from MT ! The 27' designation is the actual size of the living qtrs, that's how they classify them. You'll notice that your hood & bumper extend that extra 1'9" past your living area.
