87 winnebago refridg works on electric but not gas any help? the vents are clear of debris

Is there a timing belt or timing chain? My wini has 74,000 miles is a timing belt a concern?

I just purchased the 87 winnebago mentioned above from a private party from New Yorrk state and I am now trying to get a title transfer in PA. I have been asked to find a plate with the VIN and gross vehicle weight somewhere on this vehicle. I have looked everywhere and cannot find. Does anyone know where this plate could be? There is a plat on the drivers side door jamb but no gvw indication there.
