My coach leak down rate is certainly much higher in cold temperatures. I always have identified the push on air fittings as the culprit. In sub zero temps they are much more likely to weep air. Whenever I find a leaking push on fitting, I replace with a DOT compression fitting. I have yet to find a leak in a DOT compression fitting.
In a quick fix for a leaking push on fitting, you can sometimes reduce the leak by cutting off the last 1/4 inch of tubing and reinserting. If you look closely the tubing takes an impression from the o ring in the push on fitting. Putting virgin tubing in the fitting gives the o ring something to seal against.
A little bit of soapy water will go a long way to identifying the leak when you take it back. The air bags, air bag connections, the height control valve, and the connections to the height control valve are all suspect until checked for leaks.
