I have been shopping for a new trailer. Featherlite will install LP tanks on the outside of the V just like shown in BLIZARDICE's photo. The only other option they offer is to install them INSIDE the trailer in a sealed compartment that is vented to the outside. Essentially it is a generator compartment that is open on the bottom and has a vented door on the exterior. LP is heavier than air and will sink. They would not install an RV style permanantly mounted tank underneath the trailer.
The only good non LP gas solution I have found is the Espar heater. They burn diesel or kerosene and are vented to the outside. Only bad thing is cost. They are more expensive than an RV style LP furnace. http://www.espar.com/html/products/airheaters.html
