Of course the Grand Design owners manual says nothing about this but I have a couple questions regarding the Tank heater on our toy hauler.

First, can it be turned on with a partial tank of water in it. About 1/4 tank? We are in upstate NY with the temps in the thirties tonight leaving early in the morning
Second, does it just warm the tank or does it get hot?
Does it run on electric or propane.
Is it on a thermostat and shutoff when to a certain temp.

Like i said the manual shows nothing.
 
The tank heaters are 12 volt electric. They are thermostatically controlled and do not get hot - just warm. Perfectly safe with 1/4 tank of water. With temps in the 30s, though, don't worry about the tanks. They are a large enough mass inside a protected, insulated space, that it would take several hours in the 20s to freeze anything in the tanks.

You can create a signature block with your RV and tow vehicle information (see mine below). That way you won't have to repeat that information whenever you post or ask a question. You can create a signature by going to:
