Block heater

My 93 diesel dually is equipped with what I believe is a factory block heater, winter is comming and the truck probably won't be used much untill spring, unfortunately it will have to be parked outside as I have no room to park it inside yet,my question is,,would it be advisable to leave the heater plugged in for extended lengths of time like months at a time? I fully intend to start the truck and warm it up on a weekly or bi weekly basis, never had a vehicle that had a block heater, so all comments are welcome.choppingwood

There is no need to leave the unit plugged in, that just waists power. If you have a regulated battery charger, put it on one a month and start it once a month. I would put on a new fuel filter and change the oil before you shut it down. Even give it a real good washing, and do a valve set. Starting it weekly will not do anything positive to the engine unless you are going to work it for an hour or more. You only want to plug it in for a couple of hours before you start it, and it should not be above 45 degrees F. Cleaning the battery connections, and washing the batteries, will stop a lot of battery drain.

Also make sure you have #1 diesel and perhaps an anti-gel in the fuel system before letting it set. Wouldnt want summer diesel gelling in your tank.

Do as the other 2 have suggested.

Only need to plug it in maybe 3hrs before you want to start it. Pull the battery out and put it in the heated garage (if you have one), and keep it hooked up to a trickle charger.

If you won't drive the truck when you start it, don't bother starting it. Won't help any. If you won't work it and run it up to temp, you won't burn off any condensation anyhow.
