My solution to rack noise
Re: Mileage "non"complaint
In Mexico it is the other way around. Pemex does not allow you to put gas in your car. The attendant always does it. If you think gas is bad here... Gas has always been close to $4 there and now is even more. Most people with SUVs or Trucks do the Propane route and have been doing that for Years. For Ranchers it is a necessity since you extend your distance with Running Fuel and when you run out you switch to propane. I always wondered why it took so long for the U.S. (OEM , Law makers) to market trucks with natural Gas.
