A CO monitor is a must in any trailer, and is what I used before buying a $600 tester, if it does not trigger a wall mounted tester you should be good, the old grav furnaces were awesome for dry camping, to bad no one builds them anymore
Do a thorough visual on the furnace and pipeing for rust, , some surface rust is normal, and remember, gas preasure will affect CO, 11 inches water colum on the gas.. A full box test is not neccesary, isolating exhaust from the front of furnace and placing CO2 meter in front of furnace should be adequate, i start to investigate further at 9 PPm of CO2, 14PPM and I condem
I'm lookin for a good one for my build, so I'm not saying they are bad, just use caution
