You must have a pos R&R clam shell like me. Amazing aluminum foil side walls......not. Love the quick clamps. Fast and holds sled tight.
I started reading this last night and said screw it! If I can afford a12k sled I can afford to buy some nice tie downs. So I bought a pair of superclamps last night for $310 for a pair off ebay. Still will tie down the rear with rachet straps as I already have flush mounted d rings.
One thing that is distrubing is the guys with the enclosed trailers not at least ractheting down the sled inside. Even in a low speed accident say 30 mphs, to come to a sudden stop, your sleds are still moving at 44 feet per second. Where do you think all that energy is going to go? Right threw those walls that you guys have a false sense of security, that they will be strong enough to stop a 600# projectile, also, times how sleds are on board. Even if you put a cheap set of Menards straps on, and they broke or ripped the d ring out of the floor, it slowed the momentum down, so maybe the walls will be able to contain and withstand the impact.
Just did the math........
A 600# sled moving at 30mph and with a 1 foot crush factor, your 600# sled has the crash force of 18,274 lbs or just over 9 tons
So, another words, whatever the sled hits will have 9 tons of force behind it, do you guys think the walls of ANY trailer will be able to with stand it? At 60 mphs, it 36 tons, it quadruples!.
