The trick is mix a spray bottle with 50% apple vinegar, and 50% water, mist the meat occasionally, this not only moistens the meat, but helps tenderize it too. It adds no vinegar flavor, but don't over do it.
When I am making pork ribs especially I like to spray from time to time.
Venison can dry out quickly, so brine and use low heat. I finish to taste on the grill as to not dehydrate the meat.
I am no expert, but everyone loves my meat...haha
