I just took all of the stuff that i use on stand to the store, then went back to the packs and tried putting all of the stuff in there.. When i found one that was just right. That was the one that i got..
For all of the extra stuff that i didn't need to take to the stand i have a milk crate that goes behind the seat of the truck for ammo, latex gloves, knives, camp stove and so on.
For the stuff that is bigger and like to have but don't use often, i got a 56gallon tote on sale at home depot and a dolly from Harbor Freight. I have bolt cutters, cold gear, snow camo, and survival gear in the tote. When i get home, the tote goes on the dolly, and then the pack, and milk crate. It rolls away to the storage place in the garage and then the next time i go hunting loading the gear take a few minutes and I don't forget anything.
i have been thinking of getting a second tote to put the first one in, and then when i get a animals, i can take the empty tote out from under the loaded one and put it at the tailgate of the truck and put the dead coyotes in there. This would limit the amount of mess they make in the back of the truck.
