So I learned a little here and there about the trailer hitch. It pulls real good 65-75 miles per hour up hill down hill. But when the wind in blowing hard just have to slow down. It worse when big truck pass in high winds.
1st of all, I will have to agree with vp22er, that 75 mpg is too fast !! Trailer tires are rated for a top speed of 65 mph. Even without the tire limits, someone driving a small SUV with a 104" wheelbase pulling a conventional upright 20' travel trailer needs to be extra diligent....that means slow down and drive safely.
I haven't seen any reference to the Salem model. Looking at the avatar, it appears to have a high window in the rear, which many times indicates a bunk house. Bunk house trailers indicate kids, which adds up to more weight in the passenger compartment with their presence, along with extra camping gear for them.
IMHO, the 1st thing needed to be done here is to load up the camper, the family, and all camping gear and head to a CAT scale. 3 times across the scales will give you all sorts of information. Once with the camper and Liberty as it is setup to go down the road. Another weight with the spring bars unhooked. And a 3rd weight with just the Liberty. All passengers need to stay in their seats for all 3 weights.
The Liberty GVWR should noted on the driver's door, along with the 2 axle weight ratings. None of these figures should be exceeded, with the camper hooked up and the spring bars in place.
The Liberty front axle weight should be about the same with trailer with spring bars attached, and the Liberty without the trailer. That will show you if the WDH is setup correctly. If the WDH is not setup correctly that can cause sway.
An immediate fix that may work is to add a 2nd friction sway bar. The better solution would be to go with a WDH that has integrated sway control, such as the Equal-i-zer 4 pt, Reese Straight Line Dual Cam, Blue Ox Sway Pro, or the Anderson Hitch. The best solution might be going with the Hensley Arrow or ProPride hitch.
Update: Lou posted while I was composing this, but again suggested to slow down !!
