I prolly just call this down, and really expect to lose quite often but cannot fold due to the price on river.

Its not just about whether we figure to be ahead, but how often he is betting $40 with a hand he calls a shove with. A favor a monster here myself, but its possible he blockbets AT etc,but i doubt calls the shove if he took the time to blockbet.

Just my feel on those type of bets from routine players.

My play would be a call as well, maybe I'm losing value here though not jamming but as played, I'm just calling river bet.

This is 1/3, right? No way a $18 preflop raise with an aggro image after 3 limpers is going to narrow the field, which is the only reason to raise preflop (imo). I would make it $25.

Is anyone going to pay off 3 streets with a worse A? If so, I would bet no more than a 1/2 PSB on each street (folding to a raise). Otherwise, if people can fold an A on the turn to a double barrel, I would bet on the bigger side on the flop (~3/4), check back the turn, to bet the river. I wouldn't hate checking back the flop either taking the latter route, although giving a free card to 3 opponents is kinda sucky.

Against this particular Villain, we only have about a PSB left on the turn. Do we feel committed against him? I'm actually really torn on the turn between flat out folding (we did give him 13x implied odds preflop to setmine), calling to see what he does on the river (perhaps even folding to a large bet???), and then when he bets weakass on the river to actually shoving for value.
