Best Weight Distribution With Sway Control for Trailer With 1,100 lbs Total Tongue Weight


Hi, we recently purchased a Grand Design 285BHTS - Hitch weight 793lbs UVW 7,692 lbs and GVW 9,495. Tow vehicle is 2018 Expedition Max Platinum rated for 9,000 lbs max tow. Years ago I had an Equalizer hitch for my toy hauler. I found it to be only ok for sway, good for weight distribution, but noisy and greasy! I have looked endlessly trying to decide on the best hitch today. Not really wanting to buy a Hensley or ProPride. What do you think of the Blue Ox Sway Pro? will it be truly the best? Other suggestions that should be considered? thank you

The BlueOx SwayPro # BXW1506 is a good system but I recommend the Reese Strait-Line # RP66130 over it. While both systems will be less noisy than the Equal-i-zer you referred to, the Strait-Line has the advantage because of its sway control system.

The SwayPro uses a 4-point sway control system like the Equal-i-zer but the Strait-Line uses a dual cam system to prevent sway. This system's spring bars are suspended by this cam system (see accompanying photo) which ensures that the Strait-Line is always self-adjusting and controlling your trailer no matter the driving situation. While the Sway Pro is going to be easier to use and install, the Reese Strait-Line is considered by many to be the top weight distribution system available.

It is important you get the correctly rated system and in order to do that you need to know your total tongue weight (TTW), which is the tongue weight of your fully loaded and ready to go Grand Design trailer plus the weight of any cargo behind the rear axle of your 2018 Ford Expedition.

The tongue weight is typically between 10% and 15% of your trailer's GVWR 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 tow vehicle 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.

Since we know your Grand Design 285BHTS has a GVWR of 9,495 a fair estimate of your TTW is in the 1,100 lb to 1,200 lb range. For that you will need the Reese Strait-Line # RP66130 which is for TTW between 800 lbs and 1,500 lbs.

This system does not come with a shank so you will need one such as the Reese Weight Distribution Shank # RP54970 which has a TTW capacity of 1,500 lbs and will give you up to 6-1/2" of rise or 1-1/4" drop. For a larger rise or drop you can use the Reese Weight Distribution Shank # RP3215 which has a TTW capacity of 1,400 lbs and will give you up to 11-1/2" rise or 5-3/4" drop.

The only other thing you would need with this system is a hitch ball with a threaded shank and 1-1/4" diameter such as the 2-5/16" Hitch Ball # C40030 or 2" Hitch Ball # A-90.
