I am use to starting my old Bounder, pressing the jacks down button, throwing it in gear and driving off. This new routine of waiting for the air pressure to build is new to me. I have done it that way the last few starts though. But I seldom press the bunny button as I'm taking off.
I'm going to really concentrate and pay attention next road trip. I am pretty sure I've seen that drop in pressure from one gauge while driving although I did not press the bunny. So based on your description, that's a good sign. Another couple good signs are the comfortable ride, and both air gauges showing over 100 PSI while traveling.
Thanks for the input.
