Any Advice On Heating Trailer For The Winter?

Randy Russell

We drag a 16' Haulmark drop back box trailer that has been a lifesaver to the business every day. Inside isn't only a rolling big box store but also a good rest area too. Almost froze to death last winter - just can't seem to get it warm. Tried a portable 110 space heater - might as well light a candle.
Any suggestions for heating from anyone who basically lives out of their work trailer too? I've heard any type of kerosene or LP heater is a bad idea in such an enclosed area.
Thanks

How much do you want to spend?

You see that rectangular thing with the vent grill mounted on the right side by the helmet near the ceiling.

That is a RV furnace, Suburban SF-30-F 30,0000 btu.

Cost to install:

Suburban SF-30 on Ebay or equivalent - under $400
Propane tank - $40
12 volt Battery - $50
Hose, wiring and thermostat - $100

This furnace will heat the inside so hot you can't stand it, if you wanted.

The attached pic of the outside vents is how the vents are on a SF-30-F model. A SF-30 without the last F is the same furnace but it has the big rectangular cover on the outside with the vents integrated. The F model is a cleaner installation as long as you have access on the inside. The non F model is for when you won't have any access from the inside, like how they are installed inside a motorhome behind a cabinet, etc.

Insulate the trailer, then proceed to heat with 110v heater
