Let me share this tip with you from a local RV dealer. He recommends that you put a single ice cube in a paper cup and leave it in your freezer and check it daily to be sure there had not been a power failure at the campground while you were away for the day, or that nothing else has happened to cause the frozen foods to partially thaw and re-freeze again.

If the freezer has been working well, the ice cube should retain it's original shape. If it has melted and re-frozen the ice will be puddled in the bottom of the cup and chances are that the quality of your food in the freezer and refrigerator will be comprised.

RV Roof Inspection, Maintenance and Repair

Inspecting the roof sealant on an RV is something you should do twice a year. Why?

Because that is the likely place that a water leak will first develop. Water runs downhill, of course, and a tiny leak on the roof will turn into a major problem within the structure of the RV.

Think about this - one drip per minute (through a pinhole leak) adds up to 1440 drips per day or 10,080 drips in a week.

I don't have time to figure out how many gallons of water there are in 10,080 drips, but I think you see my point.

Closely inspect the roof sealant condition on every protruding fixture on the roof. Any cracks or thin spots can be touched up with the appropriate material. If the roof sealant is peeling or flaking in any way, then the old coating must be physically removed.

On metal roofs I use a 1' wide scraper with a firm blade, like the ones used by auto technicians for scraping off old gaskets. For rubber roofs I made a similar sized plastic scraper that won't cut the rubber membrane.

If you heat the old coating with a hot air gun, it will come off fairly easily.
