I am beyond a noob. I need to start doing more reading and brush up on my math, cause I'm barely following what you're saying at this point. I have no idea what EMT or rigid IMT is. I only chose 3/4" electrical conduit pipe because I saw a thread with a crew cab f250 on here, and that's what the member used. its also because I happened to come into about 10 6'-8' lengths of it for free through my work. so it was also a convenience thing.
Back to how ignorant I am to all of this, I was only first considering a convex cap because that's what most members had done with their trucks, in following the template. Although I had seen a couple members to flat/straight line caps with rounded edges. I joined this forum and want to do these mods out of necessity. Budget and fuel savings are the biggest reasons. I also mainly started this thread because there were things I was unsure about and can really only afford to do this once. So far, the more this thread goes on, the more I feel over my head. Not to say its any member's fault, its just showing that I really have no idea what I'm doing when it comes to the more technical part of this stuff.
