Do you bring a lot of stuff?
I could not have a 5th because we bring so much in the bed of our pick up.
I have a cap on it, and we carry two kayaks and a canoe on the roof.
We carry two mountain bikes plus all kinds of back packing camping gear in the bed -Need I say more.
Our trailer is a 25 footer, and we have never had a wind problem or wind current problem from the big rigs in thousands of highway miles.
Prior to this one we had a 19 foot trailer, and never had problems from high winds, but I did have to hold the wheel tight for a few seconds when a big rig came by at 80MPh.
I bought a new Dodge Ram last year, and the whole system is rock solid.
