I was trying to remember where i got my rack. REMEMBERED
Trailwerks online. Its an ebay store. Heres the link.

Email the company. I got my rack (6ft with tire carrier) for roughly 1,600 shipped. They have one with sunroof opening listed now for 1,999 or best offer. Also their ladders are 280 each. You can probably work a deal with them I am sure.
Good luck
