I enjoyed looking at your remod photos of your HiLo. We have a 17' 1976 HiLo. I am wondering what you used to replace the ceiling in your camper. We had to pull down our ceiling to repair water damage from a leak that began over the shower exhaust fan. The plan is to put insulation in the ceiling. It looked like you put 1/4" plywood and painted it after installation. What did you use? Thanks! I enjoyed your photos and the verses.
