My well insulated garage 35X21 is under the left side of my house. Parking the cars in the garage allows the cars (and bikes) to heat the garage in winter. In summer when it is already hot enough, I have a $4 yardsale squirrel cage fan I used to keep myself cool when working in the garage when it is hot. It also serves to blow out the excess heat from the vehicles in summer. The garage seldom drops below 50 degrees in winter, even when outside temps are in the 20s.
Just park the larger vehicle in the garage and let all of the heat warm up the garage.
Heating up a 50 gallon reservoir would cause the truck to run cold for a very long time and cost you a lot more in fuel overall. The heat in the vehile that you would lose anyway is basically free energy if you can utilize it for garage heating.
A simple solar thermosyphon heating system would also help, if you have enough sunlight to justify the cost.
