EXACTLY one of the key reasons I made it that way.... wasn't 100% sure on the location I picked and figured I could move it if I wanted to do so later.
Will try to share links below to the main components...
First the swing set metal brackets

600lb capacity boat winch

Snatch block the winch wire runs through

Heavy-duty gambrels to hold up game

Did use a few other small pieces of hardware such as heavy stainless steel eyebolts, washers, nuts, and heavy-duty carabiner clips to hold up the snatch blocks and carabiner clips to hook up the gambrels as well. Also keep a couple of thin ropes tied up to each post as it allows me to tie up the legs of whatever I'm cleaning to keep it from swinging if I'm skinning / butchering and want to keep it in a fixed position.
Have cleaned a pile of game in the 3 years since I built it including over 70 hogs and occasionally cleaning two at a time with thanks to friends willing to help if given a pig. Winch wire is rusting a bit, but still functional and in general plenty sturdy for use cleaning 2 big critters at a time.
