My travel trailer has 2 30# tanks on the front hitch that could be used remotely if I remove them for whatever reason. These are heavy, but can still be lugged around, and into the back of my pickup easier than the 100" 5' tall beast mentioned earlier.
The 20# tanks are more common, and even easier to handle. If I were going to "Winter" in one place, I would have multiple 20#, or 30# tanks (3 at least to prevent running out at a bad time).
