When it comes to Motorhomes in the 1970s, GMC was the best. They didn't just offer some butchered-up conversion vehicle. Nope! Not even close. Instead GMC engineered a marvel. While everyone else basically cobbled together some "Frankenstein's monster" with slab sides and a load of repurposed truck parts, GMC manufactured motorhomes which were sleek, well thought out machines using the vast resources a company like General Motors had the ability and wisdom to offer.

It isn't just that the actual vehicles are different. With other motorhomes, due to small companies and limited production, it is usually difficult or impossible to locate any written material for them, such as service manuals. Luckily, not only are there comprehensive service manuals available for GMC motorhomes, such as the 1975-1976 GMC Motorhome shop manual, which can be found by clicking here.., 1975 - 1976 GMC Motorhome Maintenance Manual - X-7525 and the 1977-1978 GMC Motorhome Maintenance Manual Supplement, which can be found by clicking here... 1977 - 1978 GMC Motorhome Maintenance Manual Supplement - X-7725, but incredibly, you can also get a 1973-1978 GMC Motorhome Parts Book!

Weighing in with a motorhome-sized 550+ pages, this GMC Motorhome parts guide provides you with the information you'll need to determine what parts are required and how the puzzle is supposed to fit. After decades of use, and most likely multiple owners, you may not know whose hands have been "monkeying around" with your vehicle and what level of skill was involved. It's certainly nice to know which parts and fasteners your supposed to have before taking on your projects.

This parts book is MUCH more than just a collection of parts numbers. It offers a huge number of beautiful illustrations to give you a comprehensive understanding of the parts and fasteners involved in making your motorhome function. The wonderful cutaway views do an excellent job of displaying how all the pieces, big and small are supposed to be assembled. Each piece on the diagram is numbered and you can reference that number to get a detailed explanation, such as: SHAFT ASSY.—front axle drive (RH or LH).
