Another side note while your waiting for the video to load.
I used a full 20# propane tank that weighed 36 lbs, after letting the generator run 1 hour I weighed the propane tank again, it used 4 lbs in an hour. That means you will get roughly about 4 1/2 hours on a full 20# tank, an empty tank weighs 17 lbs. Using regular gas it sez you can get up to 10 hours from 8.3 gals of gas, I don't plan to use gas so I don't know if that's a real number. You can do the math on which is cheaper gas or propane, also conceder the weight the price and the ease of use.
