Richard, Do you know the original manufacturer of the kit? Mine is a D&R when they were in Penn. I drove there with a borrowed covered trailer and picked it up myself. Yea shipping is expensive but even at $8500 should be a good deal as you're getting more than just the kit.
Looks like a lot of work was already started and if the guy did a good job and you don't have to re-do stuff that's hours ahead of the game.
Well congrats and post pics when it arrives on what you got.
