I had a local fabricator/welder come in and look at it today, he is steering me away from aluminum, in favor of 3/16 plate for the new corners and jack mounts, with diamond plate to cover the damaged fiberglass.
I'll get some cardboard templates made up this week, and hopefully have some parts back next week. Once this puppy is up on her own jacks again, i'll attack that damaged floor under the hot water and start checking out the roof for leaks.
Getting there. Slower going than I had planned but not unhappy with it.
