Sounds like you have a serious pully problem. I am extremely knowledge with auto mechanics. Usually if one of your pulleys is freezing up, it is not uncommon to experience a belt break. You can take the belt off and check to see to see all of your pulleys
Spin freely by hand. If you have even one pulley that's seized up, that would be you culprit. Autozone has parts available for these older rvs. During the summer, the heat can take a toll on engine parts. If you have the 460 v8, then you already know these older motors have a lot of heat issues the can make parts and old pulley barrings on the belt drive go bad quickly (alternator, power steering, AC, water pump, etc) i have a Dodge 440 and it gets hot under normal operating conditions. You want to get this problem permanently solved as quickly as possible. Repeated belt breaks can cause serious damage to the crank shaft in your engine and would eventually lead to engine failure. A bent crank and your not going anywhere. So it is worth taking time to find out what's wrong so you don't risk serious damage to your engine.
