My swivel pedastal is mounted right on the edge of the stairwell-and with the seat slid all the way forward, you can still get a cooler past the back of it. With the dog house on a Ford being wide, you do have to sorta climb over the edge of the seat to get into it, but you are fine once seated. With the right order of sliding the seat+ tilting the back, you can turn the seat almost all the way around. My seats are pretty poofy-and have armrests-you could make more room if you found something smaller. Here it is slid forward.
