And they are valid concerns. Learning to reduce a big game animal to manageable sized pieces is best learned from a mentor for sure but there are some excellent internet resources. I'd suggest a Google search for "gutless method of field dressing" This is what we use on remote hunts for critters from deer and sheep to elk and moose.
Having a bear come creeping in is a concern as well. We had a very close encounter with a grizz a few years ago while working on an elk. It's very rare but it can happen but if you are prepared you can typically still get your meat out without serious incident.
Being able to get meat out from remote locations definitely increases your odds of success as you are not competing with other hunters.
I'd look real close at the regs...My cousin was charged for wasting meat with this method.
You have to take all useable meat.
