Tom, What type of gas lines do you have, some were steel galvanized pipe, and some were copper tubing with flare fittings, what are yours? Both types are good for vary high test pressures, if necessary you could go up to 300 PSI, I think 3/8" coppers burst is something over 800 psi and 1/4" is much higher, not that I am recommending this, I just wanted you to know how far you are from the burst point. We tested copper refrigeration line sets at 400 PSI of nitrogen all the time.
I think your doing a great job of leak testing, and that's the way it goes sometimes, the leak is just hard to find. Look at any place the pipe passes through a wall, floor etc, or could possible touch anything and rub. It does sound like a big leak.
If you have things plugged off, you can run the test pressure on up, and if its quiet, you might even hear it leaking.
Keep up the good work, and you will find it.

Hello, Well I finally found the leak. It was getting bad enough we could smell the gas outside while camping this weekend. I got under there yesterday and wiggled on the lines and I had a big leak. The line rusted paper thin inside a plastic sleeve where it goes through the floor to the fridge just behind the back tires.
Lucky there was extra line going to the fridge so I could push the line down to get enough good line to cut off the bad end and re-flare it. A friend we were camping with ran me to a hardware store so I could buy a tubbing cutter and a flaring tool so I could fix it at the camp ground, it all worked out fine and my leak is gone.
