Crack progression: First picture is from December 2018 when I noticed that the "hairline" fracture - that had started long before - changed to a "crack" about 4 inches long. 2nd picture from February 2019 (about 5 inches?). Next few pictures - when it's really getting my attention - are from March 2019 when it grew to 8+ inches (picture when unhitched); First video (March) shows crack "closing" when unhitching from truck. Later pictures/videos (with tape showing) are from July 2019 when it cracked all the way! :( 5th Wheel has less than 10,000 miles since new!
