protection for electrical, propane and water lines

[gene so]

Hello,

I am planning to build a teardrop with a custom frame with ten inches of ground clearance on 15 inch tires on a Dexter spring axle with 6 inches drop. The frame will be 2 x 2 steel tubing. Since I will be camping mainly in the Southwest and not near organized campsites I want to protect my electrical, propane and water lines. Since I will be fabricating the tube steel frame I can drill through the tubing cross members and run EMT conduit, and pipe, through them to protect these lines. I do not know what size the fittings are for propane and water lines so I can know which tubing diameter I should be drilling. Do the propane and water fittings vary a lot?
Is there a better way to protect these lines? I have some metal skills in fabrication from long ago, but am ignorant about electrical and propane usage on such a trailer and want to do this correctly the first time!

Thanks in advance,

If you use STEEL lines for water and propane there should not be much need of "protection" remember these are going to be against floor generally in high portion of underside, for electrical you can put that in conduit, if you really feel the need to protect them, just clamp them to frame member (no drilling to penetrate members) and run a length of heavy gauge sheet metal as a "rock guard" underneath them to protect from gravel thrown up by TV tires...

For propane and water I can't see why you would even have fittings in the conduit. They should all be solid lines from source to outlet.

Its just like when you run electrical in a house any splices or fittings should be in protected box that you have easy access to.
