This is an interesting point. If I can manage to haul my trailer across 3-mile bridge without the uprights taking out the center divider poles, I think it's very fair to expect two trailers to fit on a 22-foot wide ramp.
Just so I understand it correctly ... you take up the whole ramp to protect yourself from stupid or incompetent people?[I like to ride on the dotted line so no one who might not know what they're doing can get too close to me.] I like to stay in the middle of the shoreline boat ramp for that exact same reason
