Thanks for the response Carl. When we picked up the TT and drove it home, it was pouring rain the entire 4 hour trip home. I noticed water on the driveway at the front of the TT and thought it was condensation coming off the roof/front cap and not drying. When I climbed underneath to look, I noticed a sagging in the underbelly. When I pushed up, I could hear the water sloshing around. I would say it was between 1 and 2 gallons. I pulled a 1'x1' piece off to expose a 4"x4" cut out where the installers hooked wires up. I pushed up on the underbelly and drained almost all the water, plus left the cover off to let it dry. When camping this past weekend there wasn't any water draining out. When I pulled the slide in to move the TT back a few feet, I heard water running onto the underbelly and draining out the front 4"x 4" cutout. My assumption was there must have been water on the slide and it drained down to the underbelly. I guess it could be the slide pushing on a drain or hose causing the water to run. However, when we closed everything up to come home, no water.
I plan to take it to a dealer after camping in a week to have them check it out and a few other things.
