Just for various reasons, I decided to stay with the stock (well, Flexsteel) seats. Number one being the power adjustment capability for the driver's seat. Not that I need power for fore-and-aft adjustment, but without it there is no adjustment for raising/lowering the seat, nor for raising front/lowering back of seat cushion. I wanted to maintain that ability. Even when seats are set perfect for me, I sometimes like to work the adjustments a bit on a longer trip, just for variety.
I can totally see having one for a passenger seat, especially with the door right behind it and the fact that you like to keep the cab open to the rig. And the driver's seat too if you don't need the adjustments. If you got the seats for $400 a pair, that was a really good deal. I paid something like $750, and that was picking them up (would have been more to have them shipped). Again, a quality item that seemed worth the price, but just didn't end up working out for what I wanted. And when something I wasn't sure about was worth ~$1500 (and taking up a bunch of space in storage), I decided to forego them (plus figured if I changed my mind at a later date I could buy another set).
So, I still have the Flexsteel cab seats, and at least for now, a smaller automobile seat as my "forward chair" in the living room. It swivels and moves fore-and-aft like the club chair did, plus the back is adjustable and it has arms and a headrest (which the club chair did not). I mounted it on the stock platform and swivel. Instead of a footrest I have the edge of the couch or a stool
