I am looking for advise on some hitches I saw at the Jacksonville, Fl. RV Show. There was a hitch called the Sidewinder, supposed to allow you to turn 90 degrees eith a shortbed truck without having to use a slider. They advertise on the web with a video that shows it in use. Also a hitch called the 5th Airborn, basically an air shock suspension to smooth out the ride of the trailer. Claimed to reduce chunking, although one of their advertised testimonials said it did not eliminate chunking. they also offer these hitches in a combined version, for around $2ooo. Susposedly they are made by the major 5th wheel hitch manufacturer, Liebert or something like that.
