I assume this is CO, right?
If you’re apprehensive about gutless or quartering, don’t do it. Get someone experienced to watch doing it, or walk you through it, until you are comfortable doing on your own. I can break down a deer-sized animal in any method in less than an hour. If your not experienced/confident, the issue is not how long it’s going to take, but rather screwing it up and getting the the meat dirty and contaminated.
For your hunt I’d recommend what
@seeth07 said about gutting, and cut the legs off beneath the knees. From there cut the spine in half ahead of the hips and you have your animal in 2 pieces. You can use a small Lithium battery sawzall with a 6” wood/nails blade and be done real quick. Toss each half in a large game bag and carry out one piece at a time in a frame pack, sled, or gamecart
There’s 100 ways to do it, but that’s my .01 opinion on balancing simplicity and ease.
Ive dragged or carried several deer out whole 1.5-2 miles when I was young, dumb, and ambitious. Now I’d rather not waste half a day and kill myself in the process so I’ve moved on to gutless.
