When I purchased my new Airstream in 2018, I knew nothing about accessories for the hitch. I accepted the 'wisdom' of the dealer who installed a Blue Ox 'weight distribution' device. Phooey!! Within a few months, I had my first experience with sway, which was terrifying. Shortly afterwards, it happened again, on a mountain road, going downhill. I was ready to sell everything, trailer, truck, etc. to preserve my heart and adrenal gland. Then I heard about Hensley from an Airstream group. Due to the relatively modest size of my trailer (International Serenity 23FBQ), a Cub Arrow was suggested. The light weight of the insert ('stinger') clinched the deal. We are seniors who value our lower backs. It is easy to lift and insert into the hitch receiver on the truck. Other brands were talking about lifting 80 lb....no way!! Airstream service at Jackson Center installed it and showed us how to use it. We practiced connections in their parking lot. The rear camera in the truck made a difference! Practice matters and the manual and Hensley videos were reviewed. What a totally different towing experience after installing the Cub Arrow. Holy Guacamole! No sway, no suggestions of sway, it felt solid at last, even during heavy winds, storms, steep roads, big trucks passing me at 80 mph...no worries. Also, far easier to maneuver into a campsite. Very happy after 8 years and lots of miles. Getting a new truck and using their program to get a new stinger. Good folks, excellent product that performs as advertised.
