I'm pretty sure on a wrangler you need nutstrips to put a hitch on, which are nuts welded to a piece of metal strap that you slide into the frame so you don't have to maneuver a wrench in there to hold them, or if you like working on projects for way longer than expected, getting frustrated and fitting your hands into really small places you could go without

. You can get them at the dealer or order them online for half as much money, up to you

, or someone with a welder and a few minutes free could make you some no problem.
Other than that if you have some normal sized wrenches its super easy to install, just a 2 person job since you need someone to hold it in place while you start the first couple bolts. As for brands they are pretty much all the same, buy whatever is cheapest, just make sure its a 2 inch receiver, don't waste your money on some flimsy 1 inch job. Also it helps to buy one that has little tow hooks on it for recovery, you can put the tow strap right into the receiver or get an insert, just a matter of preference.
