Not sure on the Windsport, but I just removed the drivers seat on our 2016 ACE.
It was held on with four 3/4" bolts/nuts. I used locking pliers inside the coach and went outside and reached over drivers tire with ratchet to loosen. I did raise front end a bit to gain a bit more access. Putting back together was little more tricky due to washers falling off when reaching up to start on threads of bolt. I used a small piece of painters tap to hold in place and then started nut onto bolt with air ratchet.
