Definitely! It only takes one sudden stop to get them moving... and it only takes a few seconds to throw superclamps on the skis. Do you really want your hood all scratched up because your buddies sled got a little too close?
When staying local less than 50 miles no, they have never moved even dynamite stopping from highway speed once because some A..hole had the Uhaul turn signals reversed. Signaling for a right and turned left across the centerline as I swung wide to pass. Stopped in time and he was extremely apologetic and have put tie downs on ever since. It really doesn't take that long, I use the cam style tiedowns not the cumbersome ratchet jobs. They are not going to move anyway unless you invert the trailer but even then they will stay on the ceiling!
guess been lucky... never tied em down and they dont really move, even with brakes not locked half the time.. if they are moving, your should probably settle down a little bit in the drivers seat... aside from a major "adventure" they never move on me.
for any long hauls, 100 miles or more i would probably lash them down just to keep em from rubbing from lots of chance to wiggle.
Absolutely! Have had a few times when I hit some black ice and have been sideways before I even knew it. No tie downs would have meant, damaged sleds and sidewalls in the trailer. I have got to much invested in my equipment and it doesn't take long to tie them down. I think this is just like the seat belt issue, you can go along time without wearing one, but the one time you are involved in an accident, is when you really find out how important they are!
I when traveling on the highway strap them down but when leaving the mountain heading to the hotel just leave them without the brakes on and have never had them move very much.
I tow 550 miles each way and never had a issue more than a scuff or two. No worse than riding in the trees. I figure if I roll the trailer its going to be bad no matter what anyway.
In my old four-place we never tied down...no problems. Now the new trailer we use has a composite floor that makes the sled's more likely to slide around, so we have been.
honestly every accident pic I have seen with sleds in a trailer....it doesn't matter if it is tied down...they are getting tossed. Actually I do remember an accident and the non strapped sleds were tossed to the side with little damage.
