Downed trees are a pain, especially spring hunting (bear/turkey). I have a winch, come along, and a saw to help clear rocks, trees, etc. that have ventured into roadways over winter. As stated, battery saws are no joke and can be really slick for this type of application.
December cow elk hunts are almost always winter range hunts. Nothing like "normal" September/October hunts for elk. Most are dependent on snow (more snow generally is better), cows will be in larger herds (not uncommon to see a herd of 100+). Scouting now won't be overly helpful, doubtful...
Questions (I don't have a dog in this fight): are folks upset that someone used a camera to kill a deer, or the deer? Seems the latter to me. If a hunter knew Big Pappa was available, would they be more inclined to eat tag soup?
All trucks cost money, be it a hefty payment or repair bill. I think reliability becomes an important consideration, especially if it is your recreation rig. I hate playing "fix a truck" when I could be hunting.
Pay attention to twist rates. Round bullets, slower twist. Conical, faster twist. I think that gun has a 1 in 28 or 1 in 26. Double f (ffg) for sure, given the mass of bullet. ID changed rules this year (2024), jacketed bullets are allowed, still no sabots though which pretty much eliminates...
Unless you have one of the early tags, I think the general starts after elk hunts. My point: mature bucks will be pretty locked up, mostly nocturnal at that point due to general "pressure" from a lot of hunters messing about for elk and early general deer. Depending on your unit, you might try...
Killed a few pronghorn in a couple different UT units, last was 2014 (pictured) before I moved to ID. Pressure is a lot less vs WY, people won't bug you much. This guy was really patient, as you can see my kiddos were with and didn't present an issue. Take your time, enjoy the hunt, you will...
