Thor is the "parent" company of keystone isn't it? I've personally looked at thor products and wouldn't touch one. BUT... I agee with the posters right to rant, and I agree that ALL manufacturers have issues, AND. I agree that no P-trap is a big Quality control issue from the factory. But how can the dealership PDI find that problem when there is a full underbelly skirting? It sounds like that issue wouldn't be found unless the shower was draining long enough for the water to find a way out of the skirting, and not just pooling up under the drain?
