I had Blue Ox baseplates installed on my minivan and Jeep at Tom Schaeffers in Shoemakersville, PA. I'm in Hunterdon County, NJ so it is about an hour ride for me.
They know what they are doing so it is well worth the drive. Depending on your toad, you may be cutting part of the plastic bumper so you don't want some non-RV mechanic learning on your car. Plus Schaeffers wires a separate harness and new bulbs in your tail lights just for towing. That way you don't have to worry about tapping into the existing harness and fouling up the electronics.
(877) 217-2444. Aaron in service will help you out.
