Same for me the H2 was a big POS that tried to mimic the H1, Though I never did even try to wheel an H2 I did have a friend that tried, once. It did the exact same thing that one did and is why I know what causes it. I have wheeled both an H3 and H1 both were very capable for what they are. With the flat belly the H1 was unstopable and the H3 just has to worry about clearance. The H3 sits on the trailblazer chassis just so you know.
