We have a Jayflight 2008 31BHDS G2 and it has a plastic toilet. It's still in great shape, but I'd be interested in finding about porcelain as well. Even thinking about a composting toilet mod. It would mean having 2 tanks for grey and enable longer boondocking without needing to discharge the tanks.
