Yea it do-able. Slide it all the way forward + I can get a cooler past the back of the seat-slide it back and there is limited but tolerable foot room. (depending on year/model due to width of the doghouse.) Also matters is how whatever company cut the floor for the steps.
This is the seat slid+ tilted forward.
And this is slid back showing foot room.
You have to climb over the corner of the seat a bit-but its fine once seated. I can still swivel it.
