Hey Joe - I'm in a similar situation, setting up a food truck out here in the Peoples Republic of Western Washington....
I looked at the Fast Eddies and while I like the idea, the width of the unit and the need to access the firebox from the side are deal breakers. I may have narrowed it down to the Ole' Hickory CTO.
As it will be inside the truck I like that it uses gas rather than electricity and will not need it's own separate flu as they would require here for any "solid fuel appliance" (which the FECs are as they use pellets as the heat source). On the other hand, you can also use it as a stick burner for competition.
