I am undertaking the restoration of the frame and changing out all the water and propane lines. My 1968
Globetrotter has the propane lines exposed to the elements and on hangers outside the bottom wrapping. This can't be correct. Can anyone give me their opinion? I intend to hang them inside through the crossmember frames. If I am right, are there rubber grommets available for hanging these 5/8" pipes? Also, the entire area under the floor was spray foamed. Thought they did not do that at the factory. Seems solid though. Thanks again.
