I have a 2015 Rubicon Hard Rock edition. The rear bumper has a hole in it from the factory to fit the AEV carrier. The factory bumper has a cut out for the spare, and with the AEV carrier moving the tire to the passenger side it would seriously mess with my OCD!! I decided to install the Teraflex carrier to keep the spare centered on the factory bumper cutout. The teraflex carrier is stout and I'm happy with it for the most part. My only complaint is that it doesn't allow the tailgate to open as far as it did with the stock tailgate hinges installed. I have the AT combo slide, stove / fridge mount, on the driver side and a tailgate table. There isn't much room between the open tailgate table and the slide when its out now. I'd like the ability to carry extra gas, but a 2-3 gallon Rotopax wont get you very far.
Replacing the Teraflex carrier with the AEV carrier is on my list now. If I'm going to carry extra fuel, I might as well cary enough to actually get me somewhere! And putting the factory tailgate hinges back on will give me some extra space between my tailgate table and stove/fridge.
Matt, I'm thinking something similar (replacing my TeraFlex carrier with the AEV carrier - I also have a 2015 Hard Rock). I wish I had gone with the AEV carrier in the first place, for the fuel caddy mainly. One thing I'm not super happy with is that TeraFlex won't give me a "safe operating weight tolerance" that their carrier will support, whereas AEV comes out with it when asked.
Did you go through with the replacement?
Dennis from TeraFlex and I have been in email communication and he said that TeraFlex is currently testing the Titan tank with their carrier. I have followed up with him and he's, in turn, following up to see if the tests were performed and how they went.
Dennis said that as long as the tire could be snugged up against the tank and the tank up against the hinge so that there is NO movement (which would translate into metal fatigue on the adjustable spare mount), then there shouldn't be an issue. When Dennis gets back to me, I'll post an update.
