A great fire extinguisher to have in a motor home is one that is foam based. The foam will handle wood, grease and a bunch of other types of fires. It cannot compact down to into a hard, unusable mass like the powdered ones. And they don’t have to be expensive. We did some research and now we personally use this foam extinguisher on Amazon
for around $17.00 for a two pack or a single one
for around $11.00, even with Prime shipping no less! It is recommended that you have several of these throughout your coach for easy access. What would happen if you were in your back bedroom and a fire started in the kitchen? It would be dangerous and cost precious time to run all the way up front to grab that one fire extinguisher by the door that might not even work. So please make sure you have one in the bedroom, bathroom, kitchen or anywhere else you feel one may become of use. These are so cheap (and small) that it’s easy to buy multiples and place them all over. Don’t forget the outside compartments and your car as well.
