Plastic end caps that hold the crossbar on came broken. Coleman only wanted to replace the cot but I didn't want to create more garbage. Thankfully I have a 3d printer.

Have used them with the replacement for about 8 nights and so far so good. I printed with 100% infill which I doubt is necessary but I didn't want to have to print it more times than necessary. I also printed it on its side with support so that the layer lines go from the end with the nub to the end with the cutout for strength. Again, not sure how necessary that was but its holding up.

I have a Coleman 765353 Trailhead II Military Style Camping Cot
