Update: still no joy
Well, I decided to gain some room to get at the plug and unbolted the leveling valve. Didn't crack open the lines, just unbolted the bracket from the chassis and let it hang. This gave me enough room to get the allen socket and a breaker on the plug. Then using a 4 foot piece of black pipe for a cheater, went to town.
Couldn't budge it. I am going to hold off until I can move the car. I think I just don't have enough clearance to get it to pop. Once I can move the car, I'll run the back end up on the ramps and gain a few inches clearance.
