I have a 2012 Subaru Forester(I know hippie car, but I opted against the Obama sticker they give you at the dealership

)
I would like to add a frame hitch so I can pull a small trailer and also use a rack on the back to haul a cooler and firewood when camping.
How easy are they to install? Couple bolts? Any recommended brands? The dealerships want like $600 installed and I can buy the same one online for like $200
Thanks
