^I looked at getting wunna those.
And also talked with a few Toy camper guys.
They were saying 10-14 mpg, all 6 cyl a/ts.
Of course in our hands it would probably do better, but still, I wasn't impressed with those reports as a "baseline".
10-14 can be had with the full-sized American V8 units
So I went with the Sable wagon. Mid 20's, through the mountains. I can hardly wait to see what it does on the flats...
