I had electric jacks on the Pace Arrow and, like many with hydraulic ones, I had numerous aggravating and inconvenient problems. The Beaver has only air leveling and any issues with it pale compared to jacks; personally, I would not have them. The only negative to air that some complain of is the slight movement they may notice while walking inside or during high winds, because you are sitting on air-filled rubber tires instead of solid chassis-to-ground steel tubing. After 33 years, Lee and I hardly are aware of that motion, like sailors with sea legs I reckon. A trade off, sea legs for trouble-prone, costly jack system, is not on our radar.
