Hi sledskiing,
I got an 03 Double Cab 4x4 Tacoma with the short bed, the only option there was in 2003. The bobcat goes about 1" over the opened tail gate or about 13" over the bed with no tailgate..................
I see you have the camper hanging out without support. There were old post that stated that you need to have the tailgate on or make a support for the camper hang out the back. I would checK with ATC to see how they built yours.
