As previously mentioned, it's easier to keep your meat clean and eventually cut and wrap it when you do not bone it out. However, in most backcountry situations where camping equipment is involved you'll need to bone the meat out unless you're willing to make multiple trips or have several hunters in your party. Also, on warm weather hunts boning it does allow you to cool the large chunks quicker. In reality, once you have a little bit of experience with making the proper cuts, and good meat sacks, boning out the meat from your kill is easy, lightens the load substantially, and the end result (clean cared for cut and wrapped meat) is excellent.
As stated depends on the situation. If you are going to get it out that day boning is great. But if you are talking a few days boning exposes more surface area to spoilage. It's your call.
I dont care if im 100 yards from the road I always bone out my animals. BS on it is easier to keep clean by doing it later. Take your time, I dont care if its 90 degrees out side if done right you will never lose any meet. A 8 X 8 drop cloth weighs 4 ounces, this is plenty of space to do all you cutting and deboning. To me packing bone unless antlers is just stupid and harder to strap to a pack then a sack of meat. Plus if or when you take it to the locker for processing they charge you for the total weigh which includes the bone. Only about 45 % of a animal is edible. Seems like a no brainer.
