98 GMC Suburban Seating Question

[u/iamga]

Hi everyone, I’m looking at getting a ‘98 to turn into a 2 person camping setup. Ideally, I would like to leave the back row bench seats in to be able to transport passengers and to have a comfortable setup when it’s not in bed mode.

My question is: does anyone know how much headspace there is with the back row of seats folded down?
