M.P.G.
We are looking to get a 42' M/H single axle to full time in. I was told that, that size M/H would get somewhere between 7-11 M.P.G. We just started looking at a tag axle. Can we expect better or...

I hear the tales of "10" and "11", and I smile. I need a calculator like they have! If you are over 30K in weight plus a toad, you will not see 10+mpg. If the stars align and you do, enjoy it! Most ISC/ISL class (and CAT equivalents) putting out 380hp or more will not see 10mpg. The good news is that there is a basement number. No matter how heavy, how much wind, or how fast you are going, you should not see any worse than about 6 mpg. If you drive at the perfect speed/drag to RPM ratio (for us, 67mph) on flat land without much wind, you should see almost 8mpg. We average about 7.4 mpg in Colorado, and on flats about a whopping 7.7mpg. Over 8mpg in a big coach is graaavy........
p.s. we are 42 ft long, no tag....tag is a weight thing, not a length thing.
