Yeah, you should beable to fit a full sheet in the Ford with no issues. I would also say go with the ford. If you are just looking for a truck to beef up and get more power out of, get the dodge. The cummins is an awsome motor. But if you are wanting to do more than just fly up and down the road and hook to a sled and get big numbers on a dyno, get the Superduty. Much more room, you will have the duals for heavier loads, and I think it is a better built truck overall. There is a reason Ford outsells the other 2 companies 2 to 1 with the other 2 combine.
