Pulled this trailer the other day and found that the rear height was 14 feet 1 inch. Don't know if this was a factory glitch or a mechanic over adjusted the air ride on the trailer. I spotted this at a customers dock where I back in daily and noticed the trailer was very close to the roofs overhang. I used the customers tape measure and sure enough the rear of the trailer is too high. I know what you guys are thinking I parked on the wheel chock nope flat level surface. Crawled underneath and saw the air bags were as big as beach balls and the air system adjustment was fully implemented. Had vendor make the proper adjustments and re-measure rear height 13-6. Good to go. Luckily I did'nt take out any overhead objects. Lesson learned take a good look at the air ride to make sure its not over-inflated. I'm no mechanic but was able to tell something was wrong by the size of them bags.
