I don't want to sound like I'm selling a product here, but I do want to let you all know that there is a product that will ease your mind, your arms, your butt and make a passing truck,buss, and high winds completely un-noticeable.
I towed from Mi to AZ and back last year a 2010 30' Rockwood 8319SS with a 2007 1/2ton HD Silverado using a Hensley hitch. Kind of pricey but if you are bothered with high winds and trailer sway, Check out the web site. It'll be the best money spent..
When I sold my Rockwood and got the CC 5th wheel I traded my Hensley in for the Hensley trailer saver 5th wheel hitch. Very nice hitch and I don't feel the 5er at all behind me.
I have no affiliation with Hensley in any way except that I advertise for them on my web site, but when I find something I like and know it'll help someone, I like to tell all and even plug them on my web site.
2011 Cedar Creek 36B2 ordered with outside kitchen removed and a nice big wardrobe in it's place.
Pulled with a 2011 F-250 Super Duty 6.7 Diesel Crew Cab and 8' box with a Hensley BD-3 Trailer Saver. F R O G members.
