We've had a very long, cold winter, and this spring has just been cruel. We finally had a day in the 70s last weekend, and I had planned to de-winterize my camper. So, I went up for the weekend and got everything running. I flushed the water system of the anti-freeze, and prepared for the camping season.

Then, like an idiot, I checked the weather after I did all that and saw we were having the lows in the teens for the next couple of nights. How does this happen! Where is spring!?

So, instead of buying more anti-freeze, I got a fresh tank of propane from the gas station on my way to the camper, and I turned the furnace on the lowest setting just so that it wouldn't freeze up.

This year, my family got my propane gauges for the camper. It's nice to see how you're doing on propane before it's too late. Also, camping tip: Only have one of your two bottles turned on, so when it runs out, you still have propane in the other while you get the empty one filled.

It's very convenient to exchange a propane tank at a gas station or business, but this last time really ticked me off.

I hooked up my "fresh" propane tank that I paid $23.99 for, and it was clear that a myth I had heard was actually true. They don't fill those tanks all the way. You're paying more for less propane.

When I hooked it up to my gauge, it was just barely above the LOW yellow line on a fresh tank.

It was the proof I needed. I'll never swap a propane tank again. It's cheaper to get it filled from a propane company or outfit, and you actually get a full 20 pounds of propane, not the 15 that these places scam you into buying.

LOOK: See how much gasoline cost the year you started driving

To find out more about how has the price of gas changed throughout the years, Stacker ran the numbers on the cost of a gallon of gasoline for each of the last 84 years. Using data from the Bureau of Labor Statistics (released in April 2020), we analyzed the average price for a gallon of unleaded regular gasoline from 1976 to 2020 along with the Consumer Price Index (CPI) for unleaded regular gasoline from 1937 to 1976, including the absolute and inflation-adjusted prices for each year.

Read on to explore the cost of gas over time and rediscover just how much a gallon was when you first started driving.
