Not sure I understand. I thought F meant Ford but you reference the new GM 10 speed. What truck are you going to buy? Make sure if your looking at an F450 Ford it will do the job with room to spare. The 550 may suit your needs better. Buy more than you need so you won’t be stuck like me. There is a wright up in TCM about some of the changes the GM truck will offer, take note of the changes in the bed configuration and follow there advise if you choose the GMC.
