What I was actually doing under the bus...

I re routed the radiator lines for the front heater and defrost. I mounted two 20 ft runs of 1 1/2 in grey electric conduit with 2 hole straps x 6. I mounted them close to the frame rails. The screws are ran into the cross sections (hat sections) from underneath (you can see in pics). I then ran the 1in radiator hose pipe in the conduit. I selected this conduit based on price, availability, and easy to mount.  I re used a lot of the old hose pipe, hose clamps, and couplings. I did not want to run the the entire length with one piece of hose for each (send/return) in case of hose failure, I won't have to replace a 40ft piece of hose, just a 20ft or 8ft. This was the best idea I could come up with for the re routing of the hoses. I need the front heater for it's defrost capability, and for our comfort when traveling in winter.

these old fittings used to go through the floor. I used them to get around the wheels.

broken drill bit on the second strap. lots of cussing.
