I would try to get some more details hammered out before money gets involved. Some work can be done on dates, locations, plans, than people can decide if they want to

This is my elk hunting list. Others may add to it.

Good pair of boots that you can put many miles in comfortably.
Either a good pack that can double as day pack and meat hauler, or a decent day pack and a pack frame for hauling meat. I have an Eberlestock J107, and I find it to be perfect.
Good knives for skinning and quartering. If you bring one knife, it better be a good one, and you better bring a stone for it.
Emergency kit. I have things like lighters, space blankets, Quick Clot, spare knife, sewing kit, super glue, pain killers, gauze, electric tape, etc.
GPS. You can get by without one, but I wouldn't. You can get a simple unit, like a Garmin Etrex for not that much money, and it's more than worth it.
Flashlights. I like to have a headlamp and at least one good handheld.
Maps. You'll want good maps of the area we hunt. When we decide on an area, I'll give more details.
Batteries. Put new ones in all of your accessories, and I like to carry spares for everything, as well.
Game bags. You'll want at least 4 if you get an elk on the ground. I think 5 is a better number.
A lightweight, rainproof jacket is nice to have for rain and snow.
Layered clothing. It will be cold, but you'll want to be able to shed layers of clothing when you're hiking. You'll warm up quick. But if you stop and sit, or if a storm rolls in, then you'll need to layer back up. Staying dry up there is important.
Water. I have at least one hydration bladder in my pack that I fill up before I head out on each hunt. You can also put bottled water in your pack, but I recommend a bladder of some kind.
Lunch/snacks. Bring food that is high in energy. Peanut butter and jelly sandwiches, Snickers, trail mix, etc. is the type of stuff I like to pack.
Good glass is not a necessity, but it makes a huge difference. 200 bucks can get you some pretty nice binoculars. I like 10x40.
A rangefinder is also not a necessity, but if you are capable of shooting a target the size of a truck tire, then it's best to have one. Shots up there are limited only by your capabilities. The further you can shoot, the better.
Hunter's education. The cut off date in CO is different from Texas. Look it up and make sure you don't need it if you don't already have it. I believe their date is in the 50's.
Blaze orange. You'll need a cap and a vest.
Sling. If you don't have a GOOD sling for your rifle, get one. A poor sling will wear your shoulder out. I like Vero Vellini.
Cooler. A 120 quart will easily hold a cow. It won't be enough for a big bull, though. To save space, I like to bring one big cooler. If I need another, I'll go to the nearest town and buy one.
Leatherman. I like to have a multi tool. It's not necessary, but it can come in handy.
Parachute cord. You'll never know how important that stuff is until you keep a roll in your pack. The uses are endless. This is a necessity for me.

That's just for hunting. For camping, you'll need the usual stuff. We can either get a couple spots in a campground or camp on the side of a forest road. Campers are nice, but tents work, too. I'll probably camp out of my truck. This is where we can combine supplies and bring less equipment, such as cooking and eating utensils. We can discuss all of that in each individual thread.

Of course, you'll need a rifle and ammo. If you are unsure of what to bring, just ask.

And a license. You can buy that when you get there. I like to order mine over the phone and have it before. You can get a bull tag or cow tag. Some units offer both, last I knew. I will probably get both. If you can afford it, I recommend it. On a slow year, you'll want options.

I'm sure I'm forgetting something. If so, mention it. If you have any questions, ask away. This is big country. I like to go prepared. A lot of people hit those woods with far less than I do, successfully. Some even take more. If you have a license, rifle, ammo, and knife, you can make it work.

its not that much different from any other type of hunting out of a tent.

water jugs, tent, cots, some rope, saw, pack frame, really all you need.

we drove up there last year and 3 of us had all our gear in the back of a half ton truck.

And buying snow chains if you don't have them
