You are not the only one I am sorry to say.
Our Diplomat has 4 slides. 2 of them are not mounted square in the holes and all 4 slides have rubber seals that are either broke or do not reach the slideout walls. The top rubber seals are missing about an inch in order to reach the slideout roof. Obviously this causes leaks when you get just a bit of wind and a little rain.
Fortunately our rig is still under the first years warranty and we will be going to Camp Monaco in Oregon before long.
Since the rubber seals on the inside of the slideouts are also falling off, it can get quite windy indoors when the wind is in the "right" direction.
