My drop bar was not sized correctly when I ordered from Hensely and I could not transfer enough weight onto the front axle. Roger Williams Airstream puts Hensley's on all of their trailers now and are also a dealer for the hitch. While having work done on my trailer last month they swapped out the drop bar for me and now I'm set up better. You can ask for David Tidmore and he can help you out.
