This nails it from my perspective.Here's my 2 cents on the tailgate reinforcement carriers, which the Metalcloak Sportgate is one of:
The stock carrier is bolted to just the tailgate panel. The Metalcloak, Mopar, etc. not only use the tailgate panel, but also tie the carrier into the hinges. By this distribution of weight and force, it naturally is stronger than the factory tire carrier. I feel very comfortable with my 37" spare on the Metalcloak carrier/tailgate reinforcement due to this. The JL hinges are not the same as the weak JK hinges. With the tailgate being closed 99.99% of the time, the hinges aren't bearing the full weight of the spare and anything else you have attached to the tailgate. I can see it being an issue if you drove around with your tailgate opened all the time, but who'd do that??
What I've seen from some carriers (and how some are mounting their spare), is the spare isn't pressed against the spare tire bumpers, whether the stock ones or longer/modified ones. By not having the spare against and compressing these bumpers, the spare will shake, rattle, and move, which can/will fatigue whatever tire carrier installed and the tailgate/hinges itself. It is very important to have the spare tightly against the bumpers.
Yes, rear bumper mounted tire carriers are the best, but also the most expensive solution. If I were to move to 38-40" tires with heavy beadlocks, I'd then think of going this route, but would still be comfortable with my Metalcloak carrier. The longest part of my install was adjusting the back/forth of the wheel mounting flange to ensure the tire was compressing the bumpers.
The forces that a 100 pound lever jarring up and down on the tailgate panel is the concern, not opening and closing the door (those hinges are beefy). Think- washboard gravel roads. The forces and fatigue of that panel are high.. Stiffening the pannel and being absoulutly sure the rubber bumpers are tight is key.
I have had both types.
I will not take the weight or departure angle penalty of a bulky integrated bumper carrier. I know there are different ones than the one I had on another Jeep, but it was a pain in the ass.
