It sounds like you've hit a wall and need professional help. I'd recommend that you contact a Sealtech leak testing facility in your home state (Florida?) They pump air into the rig, and spray a bubble solution on all exterior access points to pinpoint leaks. Here's a link to one I found in Florida that may or may not be close to you.

I would not guess at where the leak is from, spend $100.00 and have a dealer perform a pressure test. Fix all of the sources at one time. My dealer allowed me to observe the test and after I photographed all of the bubble locations and was able to end my leaks problems. Good Luck
The battery also serves as a DC filter for your system. Should the DC from the converter have any ripple at all the battery will filter the ripple out making your DC pure. Also any spike from the converter that might harm any DC components in your rig will be filtered out saving $$$$$. I always leave my battery in the circuit.
I just recently went through the procedure and elected to have both eyes done weeks apart. I elected for the standard lens and was 20-20 after the surgery.I have worn glasses for so many years that I figured I might be at a loss if I tried to correct the vision with implants. What a difference it made for someone who was in denial. Good Luck
