A full or nearly-full gas tank reduces the odds that you will need expensive fuel system service on your truck. A partially empty fuel tank may result in rust particles flaking off and clogging fuel filters, lines and injectors. Keep your gas tank as full as possible at all times. Never let it get lower than half a tank, especially in the winter.
Don't forget to keep heat in your truck if you park outside. If you take your base unit to a heated area be sure to remember pressure sprayers and other equipment that may contain water. Brass parts will distort when they're allowed to freeze. Don't leave your cleaning heads unprotected in freezing weather. Chemicals may separate when allowed to freeze.
And don't forget to keep emergency gear like a snow shovel, newspapers, flares and a flashlight on board in case you get stuck in a snow drift. That snow shovel can be a public relations bonanza, too, if you use it to shovel a path at a customer's home.
