Yep it's basically a supersized Toronado. And it get 10-11 mpg depending on how you drive it. It's pretty small as far as motorhomes go, short and low.
I think I'm going to weave my own wire mesh grill. I can't find what I want for a reasonable price. But I can get enough stainless wire for about $20.
The problem is the grill is so big, too big to cut from off the shelf materials.
