Pretty good plan for your first time, like the others said, definitely bone out your quarters. Take your time coming out with meat/antlers, make sure you take the time to eat, and drink while you are breaking down the animal. You start packing/biking after a few hours of that hard work, and it will catch up to you fast. An important thing others did not mention, is to bring a cooler to keep in your truck, packed with ice. Even old milk jugs 3/4 filled with water and frozen will last several days. Boned out meat in bags will fit well in the cooler, and will stay cool while you go back in for the next load. Keep a few quarts of gatorade in the truck as well, with some food to drink/snack on after dropping off a load before you go back in.
Good luck, have fun, be cautious, slow and safe, and post pics when you are all done!
