Leaving 5th Wheel for an extended Period

When leaving my 5th Wheel for an extended Period without Electric hooked up, how long will my Frig work on a full 30 Pound Propane Tank?

On low in central Fl. in the summer, empty, with an interior circulation fan was 28 days. The reason I know this is because I also wanted to know. So I filled one up and turned it on and 28 days later it was empty. And I tried it on electric for 28 days and checked the kilowatt hours. Gas is for sure cheaper.
