On my '75 coach, there is a cut-out in the floor insulation just in front of the left mid wheel for the propane line (I think).

There was enough space for me to snake both fuel lines from the tanks through there. The other option I was thinking of was to cut a notch out of the
insulation further up, along the frame, but since I had room farther back, I just used the existing one.

No, I'm talking about the main frame rail. I ran my fuel lines to the outside of my frame through the notch in the insulation above the frame. I
also have full length frame pads.

Both my coaches had the lines in the original location. With electric pumps vapor lock went away. Getting smacked in the side is a common accident
around here from distracted drivers running lights and stop signs. Consequently, I don't want the fuel lines outside the frame.

I really don't have much room between the frame and body, probably only about 3/8 of an inch. But the insulation is thick enough that, with a piece
of it cut out, there was plenty of room for the lines to go over the frame.

I have the reaction arm disc brakes in the back, so (good or bad) the emergency brake and all cabling for it has been eliminated in favor of a
hydraulic line lock. So all that stuff is out of the way. The selector valve is also on the outside of the frame along with the hoses all the way to
the front steel line.
