With the camper on the truck I'm averaging about 17 mpg. Without it, it's closer to 19 mpg wi the highest being 21 mpg.

Yup the Eagle model. Their Hawk model will also fit on a T100, but it's a little wider. I went with the Eagle because it fits flush to the bedsides. I went with this set up for go-anywhere capability and the same reason you mentioned - camping with the wee ones.
