10NL TPGK OOP Value Bet question

Villain is running 49/0/1 over like 30 hands. Flop check is really really questionable, I had originally planned to check-raise, but after checking came to the conclusion that it was a pretty horrible board to c/r in a multi-way limped pot and chickened out. Heads up on the turn, my thought process was that I really needed to find out where I was at, and the most efficient way of doing that was to lead out. If he raises I can fold, If he calls I'm really not sure if I'm supposed to bet almost any river or not. I realize that this is 10NL and I can't go above Level 2 thinking (what does my opponent likely have). He's obviously never ever folding anything that beats me. I have no idea how likely he is to call the river when beat. All this considered, v-bet this river and fold to a raise, c/f, or c/c let's say average of 3/4 pot?

My thinking for value betting here is that he's almost always going to check behind hands that are beat that he'd potentially call with. I'm thinking that a guy with these stats in a limped pot getting to this river is beat a lot more than he's ahead, but as I mentioned we have absolutely no clue how often he calls river when beat.
