I recently bought a 1976 GMC Tioga. I have been looking for a manual on the internet but have not had success. This is my first experience with an RV so I have no knowledge in the different aspects of of it, such as the stove, toilet, electrical system... thanks for your guidance.
Its hard to find an exact manual for each individual model of RV. The best thing to do is itemize your items, such as the make of your toilet (Thetford,Dometic etc.) and your stove, (mostly Dometic or RV king) and watch individual videos on you tube,, same with water heaters and furnaces. The electrical system is basic simple 12volt for lighting and 110/120 volt for a/c, microwave,and wall outlets. There are several folks on here with knowledge on different aspects,, just post a question and someone will answer it or at least direct ya in the right direction.. By the way, GMC Tioga is a nice rig,, built back when RV manufacturers took pride in what they built,, Not like the new stuff they have today.
