I watched the video and I was immediately struck at how poor of a position the stove is. If you store anything within the same compartment, you have to remove it before you deploy the stove or you can't get to it, or you'll be burned. Why have it affixed to the door?
It should be noted that this is aluminum while Turtleback's are not. That could easily account for the price difference.
I wish they has a picture of the base trailer. They list all the options and you have to mentally subtract them from what they're showing to determine what's left.
