Has anyone removed or replaced the wet tank.
How to go about it safely without a deep pit.
Even with the coach at raised full position and safety blocks I hesitate to slide under there. Suspect small leak location.

Bill, I would be very surprised to find a leak in the tank itself. I would suspect a leak at a fitting or line. I don't believe that there are any fittings in the top of the tank, they should all be visible. If you have not done so already use a soap and water solution on all the fittings. On my U280 I had the pressure relief valve just disappear and left me without air. Probably I hit road trash that broke off the valve, plugged it with a 3/8 pipe plug to get off the highway.
Good luck
