Reverse Marinco Mod
After plugging and unplugging the block heater several times this winter I can see the benefit of the "Marinco Mod" by Ponyboychris:

My question... What do you think about putting the plug on, in or near the back bumper? I always back into my parking spot (old firefighter habits) and my power connection is close to the rear. Also, not being an electrician, would it be possible to have one plug in the rear and one in the front? I'm not sure what kind of wiring or switching might be required for either option, just more thinking out loud to the thinkers out there.

The "problem" you could have is that once you have power at the one plug the other would also be energized. If someone touched that other plug for any reason they would get a heck of a zap. Best to stick to one end ot the other. Just run a good quality extension cord to the back and wire it up.

A Marinco type protected plug would be ok at each end of truck.
Someone would have to open cap to get shocked.
If someone were fooling around with my truck not knowing what they were doing I hope they do get shocked.
The extra length going to rear will add resistance so use the shortest extension cord possible. As a matter of fact you should always use the shortest, largest gauge and best extension cord possible whenever truck is plugged in. Too much resistance causes heat.
And don't forget about fire danger as in THIS THREAD.

If you do make 2 plugins, use receptacles on the truck onstead of plugs. That way noone can touch anything that would shock themselves. The just make a short jumper for the end of your extension cord that has 2 plugs. should cost more than $20 to do it all.

A lot of great ideas here. I appreciate all of the input and thoughts. After reading everything so far here's what I'm thinking...
Find a nice HD extension cord long enough to reach front to rear.
Route the extension carefully inside the frame rails.
Install a Marinco socket in the back bumper.
Leave the front section as-is so it can be plugged in to the existing heater cord as needed.
Seems like a cheap solution without making any changes to the existing setup.

I agree with Robin. If my truck is plugged in, it means it is nasty and cold out and nobody, including me, needs to out there screwing around with something on my truck. If the get a ride it is on them. People need to be responsible for there stupid actions. Besides the shock would probably be less pain than the bullet they would be looking at getting.
Josh's idea sounds very good as well.

I have seen on several snow cats in the area and on a semi the other day a chrome square bodied plug with a spring loaded chrome cover. I am trying to find out who makes it as I want to do this to my truck. I will post it when I find it.

I have the same issue with my plug cover as well. It's a press fit cover and with using it a few times, it's not closing all the way.

You can find them at most truck stops.
