Well I picked up my Designer 31RLTS today. I put 30 Lbs of air in the air bags Just before going to the dealers to Pick it up. I think that 20 Lbs would have been enough. It towed like a dream. No problems. first thing I did was to take it to a CAT SCALE and weight it. GCWR 19,800 Lbs. I will probably be adding another 1500 Lbs to it, but would still be under the max 23,000 Lbs GCWR. Thanks to everyone for your help and insight.
