how accurate are the sensors and propane sensor for levels

Some one suggested that you fill your water tank and use it for a week end and then check your consumption, well do the same thing with the propane.

In general, most fridges of the same year and model will use the same amount of propane per hour, do you have the same kind I have and is the temp setting the same? If so we filled up with propane, camped for six weeks, came home, set for awhile, went back out for four days, now back home, we have propane left, you should too.
