Thanks!On my 2022 Lariat SCREW I have appox 60 inches wide and 24 inches in length at the smallest point. This is from the center console in the rear to the small partitioned area just under the folded up seats. About 28 inches from the back of the seats. You could probably get a little more if you move the front seats up. You could also get a little more if you stack on top of the plastic partition.
I hope this helps.
