Bobbing the bed just 5 inches in the front will put your wheelbase at about 118".
Here is my old truck that was at the stock wheel base,

If you think about trying to get it to 110" your gonna have to cut the front of the bed off about a 1/4 of the way into the wheel well, and then notch the back of the cab out to fit your tires in.
