So...Finally got back to my leak after working on my pond for several months! Still no luck! Used smoke and sealed it off but not productive since smoke comes out the doors, door seals, you name it! Tried blowing it with air again and using soapy water...no luck either! Ran water out the end of the hose. Cannot make it leak on purpose! I pulled the roof rack and painted it and sealed the screws and the inserts, just in case! Haven't had rain in a while! So I've tried an oscillating sprinkler but nothing yet. Plan now? Paint the floor with undercoating/bedliner and call it good. If it leaks I will just dry it out! It's aggravating me to no end.....
