Now the BIG question: Can the seats be had
To answer your question, the seats can be ordered in cloth or leather. As you can see from our picture above, we chose to have the front seats in leather but they can also be done in cloth. We went with cloth on the sofa instead of leather. We were never that fond of leather in our cars (had it in a corvette and they were so "unadaptable to the weather") but really like the leather in the PC. For us the leather seats in the cab are very confortable and adapt to the temperature of the PC very nicely. We always had to put something down in the corvettte to either keep them warm or cold but the PC is so different.
That is what is great about PC - they'll accomodate your needs if they can and they'll go out of their way to help you!
As far as power versus swivel - we really welcome the extra seating in our 2551. I am 5'1" and Barry is 6' and it works out for us that if we just adjust the seat forward or back for each of us the mirrors do not have to be moved. Power is nice to maybe get some added comfort when driving but since we do not drive long hours (the joys of being retired) and generally sit in one location for long periods of time when we go for three or four months, the driving comfort has not been an issue. Our six to eight hour driving days are few and far between.
