What hitch do you have?
I put in a Stealth Hitch. I got the combo which gives you a 2" hitch that's used for bike racks and other things, and a special 2" ball hitch specifically built for towing. When you remove the hitch, you literally cannot see any indication that you've got a hitch. It's amazing.
I previously had a couple Supercharged Toyota Tundra's that were really only used to haul bikes to the track. Now I can tow with the Beemer, and sold the trucks. It's awesome and it does great. Plus with a 1,000 miles towing at 80 mph I got 17 mpg, way better than the SuperTundra's ever got. That was with a 900 lbs trailer with about 1,500 lbs of cargo (2 superbikes, tools, e-bike and etc).
I primarily use the Stealth Hitch for hauling mountain bikes to the trail.
