That's awesome! Had a similar experience in NE last Spring. My boss had a nearly new Chevy 2500HD crew cab diesel he was extremely proud of and had just had a remote control retractable bed cover installed right before the trip. We had called up a great gobbler into a feed lot and my boss had smashed him. The whole time we were working this turkey we were hearing one on the other side of the river losing his mind. The feed lot was only 50 yards from the truck, so we grabbed the downed gobbler and ran to the truck, my boss was opening the bed cover as we approached. We threw the bird in the bed and he closed the cover as we loaded up and took off to get on the other side of the river and get on the hot bird. Down the road about a half mile the thrashing started. This was not dying flops, it was erratic thumps like the bed was being hit with a baseball bat. After about ten minutes we decided we would have to do something about it. We pulled over and my boss opened the bed cover just enough for the gobbler to get his head stuck out of the opening. When his head popped out, my buddy grabbed him around the neck with both hands and I dropped the tail gate and the fight was on!! It took a few minutes, but my buddy got the best of the gobbler and snuffed him out for good. All in a good hunt.
