What is the latest best wing conduit to use for wires

Vans sells some lightweight tube that is nice. Mark

I put some 5/8" thin wall irrigation flexible tubing that was pretty light in the wings of my RV, it was something that was almost see-thru / milky white plastic. It weighs a little more than what Mark mentioned in the post above, but being smooth walled it makes it real easy to run any new wires. I bought mine a Orshelin's which is a local farm supply store similar to Atwoods, etc.
