hi guys. ive been lurking for quite awhile but havent posted yet. thought this would be a good first one. im one of those people who have had the rock logic hinge fail. going down the freeway one day, the only thing that kept my tire, hilift, and 10 gallons of gas from going through the windshield of the car behind me was a 1/2" safety pin i had made. the hinge had fatigued right at the shoulder that the lower bearing sits on. if youre dead set on using the hinge (which works really well, as far as the movement goes, swung very nicely even with a 32" bfg m/t, 10 gals. of gas in steel cans and a 60" hilift on it) then make sure that there is absolutely no movement in the carrier when its closed, and use a safety pin (preferably 2, one at each end of the carrier). i think that the reason mine broke was because i had about an 1/8" of play up and down in it, and the hinge wasnt strong enough to prevent forwards and back movement when bouncing around offroad. my reccomendation would be to go with a hinge setup closer to the expeditionswest tacoma. to me that would prevent much of the movement that caused to fail.
