Not much I can do about that, though! :W And by the way, some of you mentioned headwinds. There were none. Now that I realize that I have to stop for gas every 200 miles, I'm OK with it. I like stopping about every 3 hours anyway, just to stretch, pee - the usual. BTW, our other car is a Hyundai Ionic; great little car, not as goofy looking as a Prius, and gets 55 MPG at 75 MPH. When I average that out with the 12 MPG camper, it ain't all that bad a deal.Re: Shocking mileage dropA 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 deltabravo wrote: 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. Shocking mileage dropTen years ago we had a lightweight camper (don't recall the brand or model) on my Tundra Supercab with a V-6. That camper dropped my mileage on the road from 24 to 19 MPG. Many years later, we just bought a Lance 815, very lightweight camper for our F-150 Supercab with a more powerful V-6 than the Tundra had. Our mileage in driving 280 miles to pick up the camper was 21.7 MPG, averaging 75 MPH. But on the way back with camper driving 65 MPH, it fell to 12.3!!! :? What the heck? :h Any thoughts on why our MPG dropped so dramatically, and what, if anything, we can do about that?
