Those are very well made brackets - I was impressed. Just a heads up to check out how long the 2500 actually is. It will stick out past the windshield quite a bit and may mount and look funky without a full length rack
Edit to add pics - if you go with the 2500 you will loose exterior access to that side of the vehicle if you want to be able to raise the tailgate. Just a heads up, that plus the length of the 2500 compared to the 5th gen rails. The 2500 is about 20 inches longer than the 2000(shown). My 2000 is as far back as possible with letting the rear hatch open fully.
Whatever you choose quality is awesome and you will have fun. If you have little kids it is the ultimate bug free containment with a breeze lol your wife will be happy too
