My husband and I bought a 2008 Crescendo with a full wall slide in May 2008. We have now been in ten different times for repairs on the slide. The problem is still not fixed. They have now ordered the FOURTH control board for it. The third board only lasted a month. Has anyone else out there had major problems with their full wall slide? We think there may be a problem with the wiring in the coach. Any help would be appreciated. We are full timers and this is our fourth RV. Dina
