Just checked out the extended ones on Amazon. They're pricey but I'm going to get a set. I used the regular sized set on my Greystone 5th wheel for years and they really helped with the bouncing of the trailer when you walked around.
To Biker, yeah, get a set of two. That way it stabilizes both sides of the trailer, not just one.
