It is amazing at the lack of "responsibility" of some RV owners. Very few read the owner's manuals, so they have no clue how things work. They use little common sense in approaching daily life. I refer to it as the dumbing down of America.
When we had a motorhome, I filled the propane tank at 1/4 full and if it was winter, I shop for 1/2 full as the minimum. With the trailer, I watch the bottles and when one is empty, it is immediately filled. For the propane grill at home, as soon as I change bottle, the empty gets refilled.
For me the worst thing to happen is no fuel for the furnace. I hate being cold.
