I had a friend that slid off the road while coming off the mountain couple weeks ago and he was pulling a 2 place open trailer with just the front ski tie downed and one of the sleds fell off the trailer. I have a Floe pro 4 place trailer and use super clamps to tie down the skis but my question is what does everyone use to tie down the rear of the sleds. I never have tied down the rear but after seeing what happened to his I think it will be a good idea to start.
