Good variety of opinions. It really comes down to what is appropriate for your truck, climate and cleaning conditions. I don't run a fresh water tank as I am in a relatively warm climate and even if water is turned off on the outside, I can usually find it on the inside. Has never been a problem here. If I was in a rural and colder climate, I would like to have the butler setup with 210 tanks. You can fill your truck, keep it warm in the garage and make it to your job without freezing. Calls for at least 1 ton van though. For residential, most could get by easily with a 100 gal tank but for large commercial, you might be running out. I have a couple of old plexiglass pump outs that hook up in line with my vac hose that I use on large commercial. I don't seem to seem a lot of new ones on the market.
