I am lazy, generally I field dress a couple hundred yards from the house and then, skin & quarter etc. right next to the water hydrant in my yard, a quick hosing with water does wonders form hair and bloody spots. But I am lucky that I can do it at my house. I almost always field dress on the ground, don't like the guts pushing out when I am try to split the cavity open, however I have done hogs that way, skin them lying on their back and open the body cavity to where just a membrane is holding everything in, then when hanging up stick my finger in and give it a downward rip and it falls out nicely. I've never timed myself in skinning or gutting and don't plan to, I'll happily take my time, stopping to get a fresh chew of Redman (Which is the real reason to wear rubber gloves when gutting or using the non-flush facilities in the woods) and maybe straighten up to let my back rest occasionally.
