Drive Slow

According to fueleconomy.gov, fuel efficiency usually decreases rapidly at speeds above 50 miles per hour. For every 5 miles per hour you drive over 50 miles per hour, they estimate you will pay an additional $0.24 per gallon for gas.

Aggressive driving (speeding, rapid acceleration and braking) also wastes gas. Keep your RV road trip gas cost in check by driving at a steady speed. Using cruise control is a great way to keep your speed slow and constant.

Remove Excess Weight

RVs should not be over weighted for a number of reasons, and gas mileage is one of them. According to fueleconomy.gov, an extra 100 pounds in your vehicle could reduce your MPG by about 1%.

Evaluate every item brought into your RV and try to limit heavy items. Traveling with empty holding tanks is also recommended to avoid excess weight while driving.

The easiest way to save money on RV gas (or gas for any road trip) is to find better gas prices. Always use an app, such as GasBuddy, to located the best fuel price in your surrounding area.

On long travel days, check prices all the way along your route to determine the most affordable places to fill up.
