How about being able to construct a water/gasoline tank at whatever site you have? That way you could pump it into a vehicle. Basically just a liquid storage on location. Also, can we make it so we can fill containers in an RV sink?
We could use sheet metal or metal tanks. A pipe or two for a stand/pipes to a pump. Also some kind of pump of course. Electric or muscle driven.
Perhaps just add pumps for for vehicles. Then we’d have the ability to make a vehicle with no engines or what not and just a bunch of metal tanks on it with one pump.
Gas Tanker (as you can’t actually have trailers):

H = Tank

Examine the pump for to pump the fuel or water into something else or maybe to pump something into it? (Like from a river?)
And here’s Pthalocy with the utterly useless suggestion I’ve seen trucks with tankers like these, but for dairy.
Imagine, you’re excited to have found something you can store a mobile source of water in, but you have to empty it first. Hundreds of gallons later, the entire roadside is covered in milk that went sour after the first five seconds of gameplay. Hahaha.
You can kinda do this already just by installing tanks everywhere on a vehicle and then siphoning it out. Also, just building a couple frame inside your house, you can put in an RV unit and water tank and whatever else on it.
