This thread is titled , show me your Ford truck, so here goes
Here's my current truck a few years ago with a prettier driver than me.
I've been using it for at least twenty years. I only use about a teaspoon of dish soap to gallon and in winter i add alcohol if I'm going to be in cold country.Not sure why that would matter. i can’t see it being any worse than what ever is being used to keep the store bought stuff from freezing.
Then i can see why you would enjoy the peace of mind of all those cubes especially since you can charge fuel costs to your customers.I use it for towing either one of my two 16' enclosed work trailers or my 16' gooseneck equipment trailer. I tow probably 75 percent of the time. They are all work trucks
