Mine was derived from the Turtlelady Stand and like hers was meant primarily for travel. In total I have maybe 40 nights in the stand and even at 220# not enough experience with the end caps to say that they won't fail. Did just do a close inspection for possible weaknesses, deformation or cracks. Seems fine so far. I'm sure that the manufacturers QC isn't of the high level we might desire for something we're depending on to keep our butts off the floor/ground. So far I haven't of any failures, if anyone knows of any please keep us informed.
