What fuel is generally used for cooking in an RV?

Induction cookers are generally used, and few RVs use open flames. The space is inherently small, which can be very unsafe. You can bring an open flame stove for a picnic outside the RV, and you can bring a portable liquefied gas tank, which is generally only 480ml per tank. The fire lasts for 40 minutes. We have met before at the outdoor activities booked online by First Farm.

I also checked this kind of liquefied gas tank on the Internet
