Custom made plate

I wanted to share a lil project I've been working on, a pricey one at that. I wanted to be able to take my bike in the bed (giggety) of my truck. I also wanted to have 3 positions... center, left, right and a 2nd bike. I go to NC every year and I'm tired of renting trailers, nor do I want to buy one. I used the 2 bed bolts, nearest the tailgate for the plate mount. The guy that made the plate did a fantastic job and probably over engineered it. My big question is, do you think 2 BMW super bikes weighing in at just under 900 lbs (total) will be too much for the suspension on a long haul? After my first drive yesterday, I'm loving it, solid as can be! Next tues I'm going to NC with 2 bike . That test fit is this weekend. I'll be interested in your thoughts. If it all goes wrong, you won't hear about it
