As always TY everyone for helping with these issue. So yes I did find something someone had posted on t he forum showing which solonoids up front in the hwh bay are for the rear slide. I think it is valve 5&6.  so when I hear the pump running it does not sound like it is building any pressure ( does not ramp up or down, just sounds like its freewheeling ). I am goin to check the locking pins this afternoon again as you requested. So minor question, do the locking pins operate on air or hydralic pressure ?  on the hwh solonoids is there a pressure valve in it or on it ? and I will look for that  check valve you stated on the ram
