€20 NLHE MTT Deep Stacked: Overbet from maniac

Hello.

In this spot maniac (SB) overbet me Blinds 1250/2500 ante 320.
I limp. I know limp no good, but I like play in board.
MP bet x2.7 from MP. Co and SB limp and I limp this. I see in MP high range.
My preflop odds 6.34:1 or %odds is 14%.
In preflop I see very good odds and I call this
In flop SB check. I play control bet 25% pot (7500). SB call this.
Turn pot here is 46420. SB check and I check.
River maniack thinking about 20 sec and play overbet.
I think what this is too much time and not good him tells.
From me his ovebret is not strong. I show this
He show KTs
Do you play here? What do you think?

Don't limp.

Don't donk bet on such a dry board.

Continue turn.

Fold river, unless he's been doing this with garbage every time.

I would call river because in my opinion he could be like 9T or trying to get runner-runner
