A big thank you to all who chimed in! Some good insights there, with the bottom line that the Boost part of Ecoboost is mostly? to blame. Still, I really am mostly comparing apples with apples - dry weight on both campers within a couple hundred pounds, both cabovers, very comparable rigs. And actually, my MPG test was more like 380 miles, not 280, about 90% flat desert. So I don't see an appreciable increase as being likely in the future. And a 44% loss in MPG now, vs. a 21% loss with the old rig? I still don't see what can explain that big a difference. Oh well.....
Once the shock of the big drop in MPG sank in, we pretty much accepted it, as deltabravo explained: b

I bought the rig to enjoy life and have fun with, cost isn't a factor in that equation. If higher cost of fuel due to low mileage was a concern (and budget constraint), I wouldn't have bought the rig in the first place.
