Our slides on our 2015 3160 EL do not operate correctly on the hydraulics when setting at campsite for the weekend. When we try to put in the two large slides, they continually stop when putting them in. We are not sure if it means anything, but the charger reading in the camper goes down from 13.1 to around 12.8. We have to let it sit and recharge back up to above 13 again and then start the slide moving in again. Each slide may stop 3 to 4 times. We are not sure if it could be the converter or maybe the hydraulic pump. We also have the same issue putting slides out unless we travel about 150 miles. it seems like the slides do not stop when putting them out after traveling a longer distance. Does anyone else have the same issues or answers on why the slides continually keep stopping.?
