water tanks falling out
I don't know why his pics are missing, though. If you PM him, he can probably email you his pics and his fix.
The pics are missing because I deleted my photobucket account. I will send them when I find which one of my drives I dumped them on. The fix was heavier angles. The supports are under engineered by the manufacturer, Lippert Components (LCI). For laughs call them and report the problem. The him hawing and red tape run around they perform is amazing. One of the main criteria for our next trailer will be which brand/model has the least LCI stuff on it.
Rockwood uses the cheapest fresh water tank they can find. Then they jam it tight to the floor. You do not think the top will balloon up when filled??? Think again. Have the camper an inch or two out of level side to side and see what happens. The floor is oly attached to the frame at the perimeter where its bolted to the outriggers. The tank is essentially a jack and will arch the floor up if you fill it full when out of level.
In contrast the second tank I added which was made by Aplha is much thicker plastic with rounded corners and does not balloon anywhere near as much as the thin cheap tank Rockwood used. I also installed both tanks with a 3/4" gap to the underside of the floor.
