Trucks aren't necessary for transporting washers and dryers.
I have a Dodge Grand Caravan, that is the long wheelbase version. With the seats removed I can fit two washers no problem and load without a helper. With the low floor you just tilt it back and slide them in.
Hauled a lot of other bulky stuff over the years as well. V8 engines, sofas, plywood and sheet rock, often regardless of the weather.
