hi, i just bought a 83 chieftan 30' to use as a tailgate party bus, so we are trying to go through it and fix things so that we can start using it in the fall. i have run into alot of problems trying to find the right belts and getting them installed properly. any info on where i can locate a service manual for this model(454 engine) would be greatly appreciated. i noticed while looking at the site that belt problems seem to be a common problem, its nice to know that i'm not alone. more questions to follow. thanks
