How many fire extinguishers on-board?

An excellent point! One outside, one in the kitchen and one in the back bedroom area. As a son of a fire Engineer/Inspector with 33 years of service, trailers, mobile homes and I would assume RV's burn about the same .. VERY QUICKLY. The gasses this type of fire gives off is poisonous.

Let's not forget about smoke and carbon monoxide detectors and when was the last time they were checked.

It's also a good idea to allow everybody who rides in the RV to practice, at least once, with a fire extinguisher so they can familiarize themselves with how to pull the pin and deploy it correctly (aim at base of the flames).

Extinguishers should be rated ABC .. meaning it can be used on all types of fires ...

Stay safe everyone.

I have two 5 pounders, one at each door. Since it's a toy hauler with a fuel station, I have an extinguisher bracket outside and move one outside for refueling. The toy loaded in the back has it's own.

2. The factory minimum one got moved to next to the bed & was replaced with a double size one in its former location.

I keep one sitting outside every time I set up. Watched a MH in south FL burn to the frame. If a fire extinguisher had been nearby, they would've had only minor damage in the refrigerator area.
