Hey y'all, I've searched the site and do not find this addressed. I cannot find the plug for my F550 block heater. Everything I've searched, in general google style, is not helpful. I thought maybe an F550 made into a class C might be different than an F550 used for commercial purposes. Any help?

BTW, I have a 2020 Magnitude XG32 if that makes a diff.
 
If you have one it is supposed to be up inside the bumper.

I have a 2022 Magnitude, if there is a block heater please let me know. No one has ever mentioned a block heater before. Be nice to know since I live in Montana.

I'd search for a wire and plug coming out by grille, or inside engine compartment, or even a Marinco plug on the front somewhere. Usually pretty easy to find. 18/2 zip cord inside engine bay is a giveaway if it has one.

Well once the foot plus of snow melts a little I will take a look under the hood. Thanks for a general direction to look.
 
While your in there, check to see if your chassis battery is fully charged- Thor left me in the cold on that one- no bi-directional charging when plugged in, so i have to have a 2a trickle on all winter. Cheap buggers- I'd be surpriised if they added a block heater since they cheap out on adding anything.

Lucky there my chassis batteries charge when plugged in and when the generator is running.

Yes! There is one! But mine was concealed behind the plastic fascia bumper. I only found it while installing a deer/grille guard. There is no way it was accessible before. Too bad Thor didn't leave access when they put that fascia on.

BTW, The stainless, chrome guard looks fine because, behind the fascia is a pretty chrome bumper! We need that in Montana too!

I am on my second Thor bumper. You have pictures of that bumper you put on. I’ve been thinking on putting one on.
 
I just found my block heater plug under the bumper while installing a new winch bumper. There it was with a cap over the 110 plug.

We often leave for winter after temps are in negative territory. Now that I’ve found the plug, I can retire the heat lamps I have used in the past and just use the block heater.
