Tom, do you have the Stage 2 of the levelup? Stage 1 allowed for the possibilty of the frame twisting depending how you used the levelup. If so, this might be what has caused your issued with the slides. However I don't see how it would cause the slow movement. Sounds like you might be on the right track with a faulty valve. You might give Dale Fenton a call or Bob Tiedge. Bob is involved with the Levelup with Dale. He is an Engineer for Lippert. Last resort, call Lippert. If you need some work done on the trailer I would highly recommend Indiana Interstate Enterprise RV. Paul Cross id the Owner and he used to work at DRV. He is very good and knows the product inside and out. He is located at Lagrange Indiana. (260-463-8100)(www.crossrv.com)
