All you need is the cheapest hitch you can buy since you'll won't be hauling 10,000 pounds! The most you would be hauling would be maybe 80 pounds, 3 bikes plus the carrier.

We all have our personal thing about carriers, I like the hitch style, I can put a hitch on any car for cheap and not have to worry about whether or not I have to get a new carrier because the old one won't fit a hatchback, or a van, or a trunk, or a pickup truck tail gate, or a car with a spoiler, etc, etc. And with the carrier I use I can open my trunk and my tailgate without first removing the bikes and then the carrier.

The carrier that I happen to like after looking at quite a few is this one: http://thebonelocker.com/ This carrier is very strong and has a built in locking system that doesn't rely on wimpy cables or some sort of cheap padlock. But you should use a carrier pin lock to lock the receiver to the hitch and not the standard pin that hitches come with.

The first time I installed a hitch it took me 2 hours with frequent interruptions. If you do it yourself it's easier if you can get the back in up higher, but don't do this with a single jack, use jack stands, one on each side of the rear. Then make sure you block the front wheels both front and rear of the tire. Then simply follow the directions. The second time I installed a hitch it took me about 40 minutes. Also keep in mind that when installing a hitch it's made a lot easier due to the fact you won't be hooking up any light plugs for trailer lights.
