Okay went to Home Depot and found some rubber material, $12.00 a roll, 2.5' x 6'.
Got home, applied Liquid nails and then shot some staples into it, just to hold it, I then used clear silicone to seal the staples and or any holes.
I moved the tank to position it over the axle, tip from the RICA folks, problem I have now is the HD reel I have will not work the way I want it to...I think I might have to call Lori sooner than I thought....
That rubber will help. Fill the seem and cover any stables you can with some black silicone caulk. Buy a reel after you make some $$ just roll your hose up by hand for now.
It will for a little while. The thicker your rubber is the better, but all of it is temporary. We have 1/2 thick mats on our aluminum trailer fully glued down with silicons and every hole in that trailer is full of silicone and coated in it. All this silicone will be re-coated for winter shutdown.
