After hearing a fellow RVer’s tale of having the LP-gas cylinders stolen while his trailer was in storage, I decided to secure my trailer’s twin cylinders. I simply drilled matching holes in the large wing nut and the notched crossbar that holds the cylinders. After inserting a padlock through both holes, the cylinders are secure. I used a lock I had on hand for my garden shed, but the 3½-inch-long (89 millimeter) Trailer Coupler Latch Lock (1471DAT) from Master Lock would work well.
