I know a few people who have good experiences with Detroit on the electric racks, no comment on the warranty aspect. I agree at some point I would get irritated having to constantly swap racks.
I would love an intermediate option between swing set and stock. Foutz told me $3,000 seemed to big of a pill to swallow, but depending on what they are upgrading and how durable, I would/could have been on board.
I was planning on calling advantage and discussion what they rebuild in the rack and what if anything they upgrade over OEM.
