Grey water issues with new Kodiak

That sounds rather doubtful to me. I suggest that you take a garden hose or something and fill the gray water tank to where it backs into the shower again just to make sure that he did fix the problem that you had. I can see no way that the P trap had anything to do with that problem. Kodiakcanuk is absolutely right that something has to be leaking due to the tank being full and that P trap is highly unlikely to be the cause.

When they first told me I was doubtful as well. I made sure to ask them if they filled the tank to overflow and they assured me that it had been done. I checked to make sure that the tub drain was changed and it appeared that it was different. I could tell that they had filled the grey water as well because there was a little water left in the tub. I went as far as to remove the access panel to check that it was dry, which it was. I, generally speaking, don't trust anyone, much less a dealership. So far I have no reason to believe anything other than what they have told me, but Ill know for sure next camping trip. Thanks for the comments and advice BTW
