Hi Troy,
For a Saturn Vue Redline you'll need the etrailer Trailer Hitch Receiver # e98865. This is confirmed to fit your Redline model but will require a decent amount of trimming on the rear fascia in order to fit. If you're planning on towing a trailer then you'll want to pick up the T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # 118418 as well. view full answer...
Thanks for the information! I just heard back from Dexter and your axle has a 10,000 lbs capacity. For brakes you will want the Dexter Nev-R-Adjust Electric Trailer Brakes item # 23-438-439. view full answer...
