We have a Husky 16k pin box for our 5ver. The problem is that the spring on the release handle is very strong. The hitch is 5 years old and has not gotten any easier to pull. I am pretty strong and it is a struggle for me, but it is impossible for my wife to pull it. This stops her from being able to take the trailer out by herself and a group of ladies.
I have emailed Husky, but there was no response.
Has anyone found a after market product that uses electric or pneumatic assist to solve this problem? I have a compressor in the front of the trailer, so a pneumatic would be easy power. I am also willing to replace the whole pin box if needed
