Installing a trailer hitch was one of the first things I did to our 2005 G24. That was in 2011 and I can't recall the manufacturer. I searched the internet and found it, installed it myself. Frame mount and rated for over the 5000 lbs the sprinter is rated to tow. Only about $150. But you'll find a MB factory trailer wiring harness will set you back close to $250. Its necessary or you may get engine lights using cheaper substitutes. Apparently can cause voltage changes that will trigger check engine lights. I installed the factory harness myself too. If you only need the hitch for a bike rack or cargo rack you could skip the wiring harness.
