The rear sitting low is not a common air leak issue. Potential causes: the rear ride height control levers are out of adjustment (one on each side), a leak in one or both air bags (you don't say if it is sitting low on both sides), a leak at the rear six pack, or the tag axle is not getting enough air to assist in supporting the rear. Newells don't have a bunch of clearance. If someone raised the front too high, it would make it look like the rear is sitting low also. I believe 701 has the HWH suspension. if so, measure the distance from the ground to the 1" square tubing that runs along the inside of the lower body. They should be the same at the rear of the front wheel well, the front of the right drive wheel well and the front of the left drive wheel well. They should be in the 11-12" range.
