Well, yes and no, it's fresh pork yes, but, I don't think you really want to treat it quite like a butt which is a completely different "design" the ham is less fatty internally so, the breakdown of connective tissue (as in a butt) does not happen. The fat is more "exterior" so bear that in mind. Are you injecting it? That might help keep it moist.
Gee, Tim, I kind of like the non hammy taste of a fresh ham treated like pork instead of either pulled pork or ham. I might do a rub over marinade. But, that's me. My brother does them from time to time and they kick serious tongue! Delicious, different, delightful!
Have a wonderful time!
