We too have a bent leg. From research it looks like soft soil due to recent rains on a less than level area, might have been the culprit.
Our 2013 Thor Ace 30.1 owners manual says to use a 2 ft by 2 ft piece of board if the ground is soft so that the weight is dispersed more (causing it to sink and shift less I guess).
Also, I just chatted on-line with Lippert ( the mfg of ours). They say replace it don't straighten it. Supposedly in the straightening process the metal is heated and bent which, once done,causes the metal to never as strong as before. ... but then it was Lippert and they are in the biz to sell new ones. I guess that's why they only give a 1 year warranty on such an expensive part.
