I have an Equalizer brand hitch. They have weight distribution and sway control rolled into a simple setup. According to Jayco's website, the specs on your trailer (up to 525# tongue weight - 15% of the GVWR), and figuring 500# of stuff in the rear of your truck, they recommend the hitch with 10K# bars:Hitch Sizes
As far as I'm concerned, the Equalizer is the best on the market, but someone will surely disagree. But it IS the simplest when hitching up and when unhitching.
Here's the specs on your trailer: http://www.jayco.com/products/travel...-feather/x17a/
