I recently installed a propane forced air furnace in my EV, the 
furnace itself is about 9"x9"x22" it is 12,000 btu and available from 
camping world.  I have taken this thing on extensive camping trips and 
it id outstanding, we were never cold.  There are no hot parts to burn 
babies.  The vent is about 3"x7" and chrome, It is exactly the heater 
found in the new winnebago EVs.
    Best of all if you already have propane it is a breeze to install 
asuming you have space.
