We camp for 4 months in the summer. We have a Weber Q propane BBQ and a Coleman 2 burner stove hooked up to a 20# propane tank. Last year we ran the tank dry about 10 days before we left for the season.
We use the grill and stove a lot. I grill at least once a day, often times twice a day and use the stove frequently as well. We have several big cook outs over the summer with 20+ people. Last year we had a Masterforge portable propane grill that used a lot of propane. I think the 20# tank will last us the whole summer since the Weber Q does not burn as much propane as the Masterforge did.
