I have the same setup at OZ and mine was $2700 and change. I think the only addition I included was the 12V outlets in the back which I would have done myself if I had known just what they were going to use (basic truckstop style splitter). The bars are 66" so there's plenty of space for a full sheet plus load stops. The rails and uprights are removable, but you are left with the little bumps that are mounted directly to the cap. I'm very happy with this topper and if you need one that can haul a lot of weight, I highly recommend it.
