Okay guys, this is from Dirk (told ya he'd never post on this forum and he's still not):
"Thank you, thank you, thank you. This is great information and just what I needed to know."
So, he's very appreciative of the answers here. He's already clicked on the links provided and looked at the power poles and said "this is just what I need".
He also said that he's not running 50 amp and if I ever decide I want a big ass 5th wheel he's going to scream very loudly for a long time. I told him that's not happening as I have absolutely no desire to drive one of those monsters, which is why we're getting a 21 foot fiberglass trailer. He said that if I win the lotto I might change my mind. Nope, still a big ass monster to drive, regardless of how much money I have.
So, anywho, thanks much for the replies. We're not digging the ditch this weekend, but he'll start on the first step (hopefully) this weekend.
