What have I done? While on a kiteboarding camping trip to Hatteras KOA, I had to move the Popup this morning. I forgot to remove the auxiliary support sleeve for the lifters and lowered the canopy. The rear corner got stuck and while trying to unstick it, , the spring ruptured out of the tube and broke the bracket. I called the Route 12 mobile RV repair With Percy Hutchens. He was the best, didn't charge me for coming out and cutting the tube. We tried everything to unstick the spring to just lower the canopy but nothing worked...The tube in the corner just could not come down, so in the end, I had to cut the topmost tube in order to lower the canopy and drive 250miles home. I did unbolt the tube from the canopy. The hacksaw wouldn't cut that spring. The rear half of the canopy, opposite the tube that was cut will not stay down. Restless wheels in Manassas can fix anything. I save the tube perhaps the can weld that part together again if they cannot find a replacement. Why does the opposite side stay up? DON't EVER forget to remove those supports before lowering.
