I don't have one of those, but a quick looks suggests its pretty well stocked. Big and heavy, but if that's the category of kit you want, then its probably pretty decent. I always add more gloves, and more little wound care stuff, as there are some pretty decent sized wounds that you wouldn't end a trip for, but might need to if you ran out of supplies. I would also add a couple decent compression bandages, as compression can be a good way to reduce pain from swelling in some cases. And if you were anywhere that compression for snakebite is the preferred treatment, I'd add some big ones for that, but if memory serves, you are in the US, and I think the treatment for rattler bites is just immobilization, but I could be wrong. A good base to start with in any case, I'd go lighter for a walking kit, but as a base-camp or truck kit, it will get the job done.
