Hello Fellows,
I have been reading this forum for a while and got a lot of good info. I have been searching this forum to get an answer for my question but couldn't. My apology if this question has been already answered. I'm running 55 ton trailer and planing to purchase 60T. I see a lot of them have modular deck. My question is when do you shim? I do understand to create and arch to transfer more weight too...? that is my kind of question. Any input will be appreciated.
