I use the Mystery Ranch Crew Cab…Over the years I have used pack frames but decided in 09 to have a pack that would be flexible enough to hunt with all the time and then when you take an animal, (in my case usually an elk miles from the nearest road) you can load up the meat immediately and take a load out…Instead of what I have always done, which is shoot a bull, cut it up, put it in gamebags, and then walk out to my truck, grab the packframe and head back on in to go for another load. Figured out that my previous method is a waste of a trip. I have solved that problem with the MR Crew Cab. I love this pack. Comfortable for daily hunting and then its adjustable enough to load up a back ham or loin meat, and take a load out on the first run…T
