No reads, and has not been aggro so far (few orbits). Bad river call?

I don't think your ahead enough to call here.
With no reads and no signs of agression I fold.

Basically all you are doing if you call here is turning your QQ into a bluff catcher (and not a very good one at that.) The only thing you beat on this board is complete air, or a one pair hand that isnt a King.

TERRIBLE RIVER CALL

I'd bet/fold the turn a lot, he's going to have a lot of pr+straight draws that will peel the turn for another bet

I don't like checking behind on the turn. If he's drawing, he'll need to be calling preflop raises with T8 to have made his hand. He's called twice pf, so it looks drawy or PP looking for set. We don't yet know he has a K, Axs+, 89 type hands are still calling that flop bet. I'd bet ~3/4th pot on turn. He's checked to you. If he has a set and is planning a c/r, that's dangerous for him. I don't think he's doing that. If he comes with you, you're probably behind but you've avoided giving away a free card to beat you and you know more about villain's holding.
