I also use the NSA Readybrake tow bar for my Jeep. The tow bar with built-in surge brake was $1000, and a Blue Ox base base plate was $357. The Readybrake tow bar has different end brackets available for Blue Ox, Demco, and Road Master base plates, so you can choose the brand of base plate that is best for your vehicle.
The base plate installation, brake cable connection, and tail light wiring took several hours, but was not very difficult. I had never installed one before, so I took my time and repeatedly checked the instructions and videos.
Shop around for the best pricing. I found that RV parts suppliers are sometimes cheaper on Ebay than their own websites. The NSA website shows the suggested retail prices.
