$11 NLTRN: Facing a river shove with trips

[Somekid]

Can I fold this? My opponent was loose, but I wasn't sure if my opponent was aggressive or passive (probably somewhere in the middle, but this was the 4th or 5th hand so i didn't have much to go on). I really had no idea what to do on this river. I figured my opponent was calling on the flop and turn with something weak, as we had already played one hand where he won a lot of chips after calling with a weak draw on the flop and turn and hitting on the river.
