Repairing the RV October 15, 2018 by Dogger We had a bit of a leak, and I got on the roof of the RV to see we had lost a cap on one of the air tubes, and the lap sealant had cracked.. well.. Chief and I went out and climbed up top and fixed it all up! Houston, we have a problem.. the cap is missing and the sealant is all cracked Gonna need some self leveling caulk, a scraper and some cleaner… Chief waits for me down by the car Finished All done
