Looking for a propane heater for tanker trailer

Why would I want to raise the front higher then the back?
The back is where the valves are. And need to be kept free of freezing material.

And this is for overnight parking. Measures aren't needed during the working day. Only parked at night.
Things freeze up. I need to unfreeze. And I"m clear for the rest of the working day.

 

Yes. I always dump the airbags when unloading.

Other then liquid loads to flush the trailer. There's just no way to completely unload noodles. It's impossible.
The trailer is 53 feet long, has 2 baffles, and holds 7000 gallons.

There's going to be dead weight. No ifs, ands, or buts.

Best that can be done is to brake check in reverse. But that's not an option anymore.

 

Truck parks at Dannon. No electricity.

First load is usually Nestle. Possible electricity.

 

Dannon has hot water. But the drivers won't drain the hose after they're done so it freezes up. When January hits. Water is shut off.

That was my first plan of attack last year.

There's a car wash that semis can fit in on the way down for first load. But it's cold water. I spent $20 with vacuum pump running chipping away at the ice inside the valve and tube. Last year.
