1. Yes and no. We have to modify the floor slightly on the passenger side. (Passenger seat is 2" further back than driver so we have to notch the floor to allow for the swivel) We started that floor modification about a month or two ago. The 3170 that was purchased was one of the first ones to have that modification, so it was set up for the swivels...but it was not optioned from the dealer. Driver side, nothing special needs to be done if it was a Ford factory seat.
2. I'm not sure if you can buy them from Atwood or not. I'll check into that.
3. I'm guessing about 50 lbs for the pair.
