I recently installed 2 new group 27 batteries in a new rubber tongue storage box on the front. I'm also installing WaveIII heater and there is a 5 lb
propane tank in the box also. I have installed 4x 2" round wall vents by the batteries and one 3" floor vent directly under the little 5 lb tank for ventilation.
The only time I'll be using
propane is when I'm not hooked up since the trailer is all electric. So the issue of having
propane inside the box while the batteries are being charged and off gassing will not be present. Is/are there any other issues I'm not aware of? Thanks for your input.
