i have a 2011 silverado 1500 with a 1925lb payload. I was thinking ,ore of that style of a deck to keep all the weight off the front. I'm not arguing here nor there mines a 6.2 gas with 2 pro chassis sleds would i be ok? What about if i towed a 2 place trailer with the deck on. Honestly I'm getting a enclosed soon i was more curious then anything.
