Freightliner air leak
[Jim M] Wayne: thanks for the comeback. I have since taken it to Freightliner who found 3 leaks. I had one airline leaking in back and both front leveling valves were replaced. I am picking it up today-hopefully. Freightliner confirmed that it should stay up at least a few days. Afterall, there is a lot of stuff, valves, fittings and all manner of mechanisms connected to the system, and air is notoriously hard to hold behind O rings and such. So, no system can be leak free, just leak slow.
