Drake is right that the removal and replacement of your HWH should be straightforward. However, be careful about using yellow Teflon tape on the gas line connection. Whether or not you use yellow tape (or any tape for that matter) depends on the type of fittings that Sunline used for the gas system. If they are ordinary screw-type fittings, then using yellow Teflon is just what you want to do. However, if they used flare fittings, do NOT use tape on the male threads of the fittings. Flare fittings are identifiable by their unique shape. The end of the copper line of a flare fitting is distinctive; it looks like the bell of a trumpet. No tape or thread sealant of any sort is ever
used to make up a flare fitting joint. The integrity of the joint derives from the interference (i.e., very close and tight) fit of the flared copper line with the corresponding brass male fitting.
I'm only saying 'If' with regard to this because I don't know what sort of set-up Sunline used on your vintage trailer.
Hope this helps.
