Hydraulic landing legs

[Mogolfers]

We have had major problems with landing legs coming up then drifting to ground again during our trip to the South. Lippert thought it was a "O" ring leak. The space shuttle had that problem in the cold when it blew up! Anyone else had this problem during cold temps? Crist RV in Mesa did not want to help us (even under warranty) because Lippert hasn't been paying warranty work back to dealer. I guess were are orphans. Beware when traveling, as all dealers do not care, some told us it would be a month to get us in. Everthing is OK now in the warm temps.
