Tongue set up

[gisclair615]

Finally installed the tongue box. Now time to figure out how to secure my battery and propane tank inside of it.

I'm finally to the part of my build where I need to mount the battery and tank on the tongue.

Any issues putting both the battery and the tank inside a tongue box? Looks like a number of folks on this thread have done that. Any need for ventilation?

I'm no expert but I believe Venting is recommended if your charging your battery with the tongue box closed. The battery gives of a dangerous vapor when being charged. Someone else will chime in and can give you a better answer.

Maybe it is just my paranoial, but I do not want my propane tank in the same enclosed area as my battery. I can just visualize the interaction between a spark and propane gas.

The battery needs to ventilate up to disperse the hydrogen that is produced while being charged. Propane needs a bottom vent as vent any leaked propane which is heavier than air. Hydrogen has a much wider flammable/explosive range of mixture than propane even though they both fall in the same NFPA class. The good thing about hydrogen is it will most likely disperse through lid looseness. Propane will collect in a bottom sealed box though. I would not place propane in a bottom sealed box. Have a look at the propane cylinder compartments found on some trailers and you will see they have open bottoms. If the box is open bottomed I would not have much worry about sparks.
