Camco 25523 RV Screw-Mounted Bubble Level

When I first saw these Levelers I was doubtful about them being very accurate when I installed 8 of them, on each corner of the camp trailer, while using a level to place the Camco bubble level while adhering silicone caulk to mount it in place. I then let the silicone bubble levels cure for two days before using them. The true test came when I went to level the camp trailer and to my surprise the Camco bubble level was dead on. After traveling with the camp trailer the levels never came off and are still affixed to the trailer. I would definitely buy again.
