I need a Receiver Hitch?

I have a 2003 Tacoma double cab. it didn't come with a receiver hitch and I would like to know what/where to get a good one?

 

wal mart or any where. most are about the same quality. now the drop or rise you need will depend on the trailer. you want the trailer to sit level as you can when it’s loaded. if the tong is a 1” or 2” high thats ok as well, you do not want the front of the trailer to sit lower than the rear, if it does you are likely to get a lot of swaying when braking or just driving.

I have a 2” drop or 3 1/4” rise.(thats what it says, it depends on how you flip it) i have it set for a 3 1/4” rise, because when i have it drop 2” and load the trailer it sags and sits with the front of the trailer lower than the back and does not tow as well.
