It's one of those ones with two rear bench seats that fold into either a picnic table or a bed. I wanna remove the rear one. There's 4 bolts underneath it on the rear. Those might be something, but no way to tell.
they're usually bolted down, do you have a picture? if all else fails you can just take a cutting wheel to them.
Mine had quick release levers, and only left a flat plate on the floor. I added a runner right over the top of them, and done.
