Got a blonde question. Is my gas tank super small?

I had a quarter tank by the gauge when I went to fill up for my first time. I thought it would be over a hundred dollars, if not even worse. It topped out at less than $50! Is that possible? I don't have a generator, it's a 27' "mini" motorhome, 1985, Rockwood. Chevy G30.

Am I going to be needing to stop for gas every 4 hours on long trips? I'm just wondering if this could be a replacement gas tank and they put a smaller one in place of the original one.
  • Chevys of that era that were made into RVs came with a optional 33 gallon tank.

    No, not a blond moment.


    Crawling underneath and looking at the tank is a very good idea. I've run out of gas in two Jeeps (one borrowed and one rented) where people had high centered the gas tanks on rocks and pushed the bottoms in. On both of them, the gas gauge worked down to about 1/3 of a tank and then the float arm was resting on the bottom of the tank. Maybe someone was bad at backing up and drove the MH over something hitting the tank. Stranger things have happened.

  • So what does the owners manual say the capacity of your gas tank is? I'm guessing you put in about 22 gallons and have about a 30 gal tank? You'll get about 300 miles at 60mph, maybe a little less?

    I doubt if there's a smaller tank available than the factory original or anyone would have put one it it. Everyone, including you, is looking for a large tank.

  • I owned a Class C that only had a 25 gal tank. I had to plan on stopping ever 200 miles.
