you should have your fire extinguishers serviced at least every third year.
some of the cheep ones never work out of the box.
gauges can be bad. saying no psi or has psi when there is none.
in a rv/any motor vehicle do the tip and shake every six months.
get at least one five pounder --A,B,C-- rated. main living area.
and one two pound haylon (kitchen/computers/electronics.
one two pound dry chem again --a,b,c, rated for bed side.
THIS is the min in any rv.
the dry chem makes one he11 of a mess, will corrode alu. but is very safe, non toxic. (it is only a form of baking soda).
but please everybody take a class and learn how to put out a small fire the right way.
