Recommended Weight Distribution System for Airstream With 7,600 lb GVWR


Greetings experts, I am considering a sway control weight/ weight distribution system for my 2010 27 foot FB Airstream International. I will be pulling it with my 1998-1/2 Dodge Ram 2500 with a 24 valve Cummins 5.9L Diesel. I like a lot of the features of the Blue Ox system but do not have any experience with a weight distribution system and would appreciate some guidance. Can you tell me if you think this is a good system for my combination of trailer and truck and, if so, which set of components do you recommend? Specs on trailer are as follows: Dry Weight appx. 5,900 lbs. Hitch Weight appx. 770 lbs. GVWR 7,600 lbs. Hitch Ball Height appx. 18 inches. Thanks for your time

Greetings. In regards to a weight distribution system, in order to choose the right one you will first need to know your total tongue weight (TTW), which is the tongue weight of your fully loaded and ready to go Airstream plus the weight of any cargo behind the rear axle of your 1998 Dodge Ram.

The tongue weight is typically between 10% and 15% of your trailer's GVWR (7,600 lbs) but you'll want to verify it by using a scale such as the Sherline # 5780 or by using one of the methods outlined in the help article on determining tongue weight I've linked for you. From there, simply add on the weight of the cargo behind the rear axle of your Ram and you'll have your TTW. The ideal system would be one in which your TTW would fall somewhere in the middle of the weight distribution system's tongue weight capacity.

With your Airstream's GVWR of 7,600 lbs, it is reasonable to think your TTW will be in the neighborhood of 1,200 lbs. There is a Blue Ox systme that would work for you, the Blue Ox SwayPro # BXW1506, which has a total tongue weight capacity between 1,000 lbs and 1,500 lbs.

The Blue Ox is a good system and will work so long as your Airstream has a frame height of between 3" and 6", though you would want to use brackets # BXW4021 if it was a C-channel frame. The SwayPro uses 4-point sway control to prevent your trailer from swaying via friction in the swing bars. It uses clamp-on brackets and has a unique feature with the necessary tilt of the system's head already being built in; other systems require you to use washers to achieve that tilt.

This system comes with everything you need for installation except the hitch ball itself, and for that you need # C40030 for a 2-5/16" ball.
