I’d take a big chest freezer I could just drop my quarters in. When you take things off the bone like that it exposes a lot more meat and you’ll loose way more when you trim to process. YMMV I don’t leave home without the freezer
Two 120qt coolers will hold a bone in Bull most of the time for me although one NM bull, boned out, filled both those coolers to the brim.
You can also take the lower bone off the hind quarter and shorten it way up.
