Or for half the price at a metal supply shop.

Jon, how far, laterally speaking, is the base of the hill from the mouth of the oven? That seems way too far away to comfortable work the oven, imo. To be able to see what's going on, and work with a reasonable length peel, you're going to want to be able to work within 12" of the oven mouth- not all the time, but you're going to want to get close to the mouth occasionally. Right now, if you're standing at the bottom of the hill, if feels like you're about 5 feet away from the mouth. My shoulders hurt just thinking about the length the peel and it's weight.
