That dude is all of 285 if not pushing 300. He is so big it makes it look like he is thin in the hindquarters, but I don't think he really is, just based on his length. Thick barrel chest makes up for "thin" hindquarters.
Basing my largest to date and the truck bed it laid on, this one is more than likely over 300#
How many guys did it take to get him on that tailgate?
