This is actually my third order. My first was over 5 years ago and they were a direct replacement for my truck cover. Over time they got tired and I ordered a replacement. Unfortunately the 2nd set (order) fell out of the shipping tube so the USPS shipped and scanned the empty tube. There are no elevators. I contacted the seller and he credited me the money for the purchase. I then reordered and received this set (3rd order) and they were excellent. I highly recommend.
