Something I found a little while ago. Keep in mind this is showing the effect of drag for a non-towing pickup! It is not showing MPG effects. There are lots of thing that affect MPG.

One thing, on the second tailgate test of Myth--Busters. The difference between gate up and down was very little. The best gas milage was from no tailgate. Not because less drag but less weight.

There are SO many variables in mpg tracking that any small difference is statistically insignificant...

tout it all you want, but it's just bench racing 99% of the time... and imho not worth the cost of the unit...

BUT, it's your rv and your money, so FAR, what you have left after taxes,
you can spend it where you want...

If you really are sad and think nobody cares, just try missing a few payments ! '11 Monaco Diplomat 43DFT RR10R pushed by a Demco Excali-Bar II hitch which is pushed by a '14 Jeep Wrangler Unlimited Sport.
