I've been finding myself hauling some heavy loads more often than i used to, from firewood to construction equipment. My Cousin borrowed it to move some firewood and i noticed the Shock was leaking (guessing he had half a cord,2500lbs or so in the bed). Im looking to replace them with something that can take a bit more abuse. Any recommendations? I dont really feel like doing helper bags. What are some good options? Probably going 2500 next time
