Don't let the negative attitudes sway you. You ask for opinions on repairing the headline - not the Rv on total. I did my headliner and I did remove all of the cabinets. Never again. Some of the screws came down from the ceiling junctions at the walls. I had to use a sawall to cut them off flush. I too believe you can trim the headliner right up close to the cabinets and install a new headliner. I bought mine at a auto interior trim shop. I think it cost about $9.00 per foot it was wider than the rv, so it was just a per linear foot cost. It was identical to the stuff I removed. That type of material is very prone to thermal damage.
