14'6" will work, but you will have to dump the load between trusses. You will have to move forward at the same speed at which it dumps, but it can be done. We need 17ft on our machine and the sidewalls of our sheds are all 16ft, but the trusses are 7'6" apart, so it works pretty good. A higher shed would be nice, and given the clearance you could add an extra row on the top of the stack with a grabber.

The other thing that can be done, if you want, is to leave the last 3 bales that you would load on the wagon in the field. You'll be shy 3 bales on the load, but you will gain quite a bit of head room when it dumps.
