I have a 17 km24 w/39000 miles original owner.
No stabilizers do not need be down. Coach and chassis battery isolater is located under the driver seat is round and has 4 leads 2 of which are 4ga battery cables. House batteries should charge from alternator while traveling. If they aren't and there are no loose cables it is the isolater. Just changed mine last week. One of the cable attachment should signs of the plastic melting. Replaces with a heavier duty one from NAPA. Slide can be open partially, but no recommended. We open it partially to unfold the mattress in rest areas and such. H
