Default Battery Draw

A week goes by and when I went to get in the truck I noticed NO dome light on, put the key in the ignition and the battery is stone cold DEAD.
My question is with the trailer connected will it still draw from the battery?
If so this would explain the dead battery, but never had this happen with
any other truck or controller. Anyone have any experience with this?
Hello I have been in the RV service business since wooden spoked wheels ( feels like it ) The draw from the trailer battery could be, Lp leak detector, refridgerator brain, Radio memory, Thermostat off swith not set to off and temp drops at night and furnance runs. The trailer plug has a 12vt power wire constsntly connected.When plugged together what draws from the trailer battery also draws from the truck battery. Problems isn't the truck but whats on in the trailer. Try looking there first. JC
