Thanks for the response mate. I've seen a few vids on how to extract the whole carcass;

I'm not a huge bloke, and this is another reason why I thought it would be more practical to only carry out what I can eat. Even considered boning-out shoulders and neck on site (weather and time permitting) to minimise load-out weight.
I don't see any reason why you couldn't take the neck out in one piece (bone-in), or bone it out, along with tenderloins and offal (heart, liver, kidneys), without having to gut the carcass, all on site; I've seen a few vids on how to do this too.
What is the advantage of carrying a full carcass out when you're going to biff the head/spine/pelt/hooves? Maybe because you want to mount the head as a trophy, or use the bits you're not going to eat yourself to cook-up for dog tucker?
