I thought that these tanks had to be plastic welded. Also it was actively dripping and wasn't sure it would seal on wet surface. The Belly pan was just dropped down on the curb side since the street side has the propane pipe screwed to the frame on that side and that was a can of worms that I didn't want to open just yet. We are holding flushing till toilet is full then we start power flush and then flush toilet three times each full to the rim. The tanks are mounted length wise side to side. The gray is in the very front, the black is just below the wall between the laundry and bathroom. The Galley tank is behind the wheels and the fresh is just in front of the bumper. I will be posting more pics of this project as soon as I finish showering..
