After having our Landmark in for an axle alignment and straightening, I was under the rig looking around at what they had done, I happened to notice an area sagging down behind the axles. I have always had a bulge there since we have owned it, 2 years now. I have tried pushing up on it in the past and had no movement. Thought it was normal. Well now it is really sagging and has pulled the skin down enough to be able to look inside. I can see the OSB that is under the fresh water tank. I cut the skin and proceed to get the water tank back up where it belongs. The 4" strap that ties the front and back support together has lost the pin that holds it in position, allowing the OSB to sag and pull out of the front and back cross supports. A terrible design by any standards!
You can not get a new piece of wood in place to support the tank with out cutting out the cross supports. Not going to cut anything out and try to weld it back together, too much to try and keep from burning up. I took a piece of Advantech OSB, highly moisture resistant and has a 50 year no seam swell warranty, cut it to size, then cut it in 2 width wise. Then I cut 3 pieces of 1 1/2" x 1 1/2" x 3/16" angle iron long enough to go from the front to the back cross supports and sit on top of them under the Advantech under the tank. Spot weld them in place to keep them from wiggling out.
Now here is the good part, while going about my repair, I noticed that there is 4 vents in this tank!! That is 4 of them, why????? There is one in each corner, no wonder I couldn't keep any water in it. There is 3 that go from the right front, right rear, and left rear upper corners trough the skin and dump on the ground. There is one that goes to the gravity fill, this one I understand. But why is there 3 to the ground???? We frequent parks with limited facilities and go to the races that have no facilities at all. We live in the Ozark mountains, nothing is flat and every where you go is uphill. It is no wonder we loose 2/3's of our water before we get anywhere.
I am going to remove 2 of the vents to the ground and installing a valve in the one I leave in. Now at least I can have a way to keep my water on-board instead of leaving a trail down the road!
