Okay, I’ll wade into the fray…
1. Yes, Gasbuddy is a useful app; it can help you decide where to fill up the tank for the least $$ along your route. Research ahead to determine the cheapest locations. Buy gas in Lee Vining, CA? Fuggitaboutit! The station at the end of June Lake Loop is typically $0.30 or so cheaper per gallon. But you wouldn’t know that if you didn’t do your homework.
2. As stated by
@MOAK, slow down and use cruise control to improve gas mileage. Also, accelerate slower and on the highway, coast the downhills. A lot of vehicles have a display that shows when you’re operating in economy mode; try to keep it there as much as possible. Ease up, Leadfoot!
3. Plan your trips and routes to be as efficient as possible. Direct routes, easier topography, highways vs. stop and go through towns and stop for supplies along the route rather than making a separate trip later. No unnecessary trips.
4. Keep your vehicle in optimal condition - tires properly inflated, maintenance up to date, etc.
5. Reduce rig weight by packing lighter, bringing less optional items, and carrying less water if you’ll be in a campground where it’s readily available. Liquids are heavy! If your RV has grey/black water tanks, empty them before extended drives.
6. Anticipate and accept the pain at the pump. Calculate the cost into your budget and if it’s untenable, stay closer to home.
Finally, turn off the TV, Twitter, or whatever medium is feeding your anxiety. Take a walk with your dog, spend quality time with family or friends, read a book, wash/detail your truck - whatever gets your mind off this subject for a few hours. RELAX. We will adapt and overcome and eventually triumph. We’re overlanders, right?
