The way I see it is the extended recievers or putting in extensions are fine and necessary if you want to use a bike rack or something, something that doesn't even really test the hitch. But as soon as you hook something heavy up, all that extra leverage isn't good nor was the Jeep/tow capacity designed to be used with all the extra leverage. I think the safest method is the OE hitch and if you need to, flip the tire carrier over. But like I said, I've had no space issues (don't even flip the tire over). But I'm lifted and can run a bigger drop (about an 1" more drop) Just my opinion.
