Just a note: We parked our ES in October and opened everything up for the winter season. Last week, March 1st, I pulled the slides in, so that I could add air to the tires. I decided to pull the BR slide in just to check operations. All three slides functioned the way they were supposed to. With the ES sitting lsince October, we have experienced NO change in level, so the hydraulics have held pressure at both the front jacks and real stabilizers.
I probably should not have posted this, because I'll probably find the front sitting on the ground tomorrow
