Pilot and co-pilot captain chairs need to be repaired. The pilot seat will swivel but then return and lock in place off-center.
Both seats have excessive play and rock back and forth several inches. I am presuming the power seat bases require replacement. I called Newmar, bases are $1100.00 each but again the bases they have may not be the correct ones, and was advised the seats may require more parts than just the base. Flexsteel RV division is no longer in business. I also looked online and parts are limited.
I do have a service contract and contacted my agent. He advised if parts cannot be had will have to replace the seat. If one seat can be repaired and the other cannot then only the one seat would be replaced. IE miss-matched seats!
