I may look at the other options besides galvanized conduit.
I really don't like comparing a teardrop with a house, because a house isn't bouncing down roads all the time.
I haven't done a whole lot of electrical work, so my knowledge of what to use is somewhat limited and that could easily spell trouble for me.
I'm going to be very cautious and careful with how I proceed with my electrical situation because I've had a close call once back in high school when I re wired an old pickup, I blame myself for an electrical fire that happened because of not doing something right on that old truck.
On a brighter note, I have a brother in law who is an electrician for Kenworth, I'll be pickin' his brain.
(I've helped him out on several glass situations, so now he can bail me out if needed)
My reasons for using conduit are two fold...
1. Ease of accessing wiring should the need arise.
2. Fire protection. (using metal conduit)
I never get calls to replace glass in trailers after a fire... because all that's usually left is a heap of burnt rubble....
