I have a Or-Fab Carrier with two Jerry Can holders....I love it. Yes, it sticks out a little, but it's not been a problem, I don't try to climb walls.
Installing it was a bit of work, getting inside the body panels thru the tail light holes and installing bolts and nuts and getting tools inside to drill holes and install the brackets was a challenge at times. But having done Maint. work for 30 + years I had the tools to do the job.
I suggest if you decide to buy one and install it yourself, you buy a 1" hole saw from Dewalt,( Lowes or Home Depot ) get the one with fine teeth, makes a very nice clean hole in the body panel.I sealed mine with Grey RTV, matches the paint...
I have not had any trouble with mine, solid as a rock even with the spare and two full Jeep Cans...Swings easily.... Be prepared to wait, there is a long line, unless you shop around, you may one in stock someplace....I had to wait 4 months I think....
