Gas can mount on top of spare tire on back wall of trailer

If you already have a good way to transport your gas for your generator, stop reading – this post is a waste of your time.

But if you have a very small trailer with the spare on the back and no good way to transport your gas can (a fairly common set of circumstances), this may be of interest.

This blog post lays out, step by step, how I built a secure mount for the gas can. Here is a picture of the finished product:

As you’ll see if you read the blog post, this mod results in greater stability for the whole spare tire assembly – it reduces the road vibration substantially. Fair warning -- the blog post has lots of detail and lots of photos. Here’s the link:

Gas can on top of spare tire
  • Blazing, it's as safe as I can make it -- very stout components. But I am bothered by the idea of a severe rear end collision busting out the back wall of the trailer, which would almost certainly cause the gas can and its "secure" platform to fall. Not likely to happen, but not a pretty scenario.

    The fact that it is a gas can would not be visible to a following driver -- the whole thing is up pretty high, and the can is recessed inside the milk crate. A trucker might be able to see into the crate to tell what is inside.
  • :h

    Dan, why can't you just carry the gas in the back of your tow vehicle in a steel safety can like the style showing in my link?

    I assume people do this all over the country in their SUVs/sedans whenever they have to go get gas for their lawn mowers, chain saws, etc. - not everyone has a pickup truck.
  • phil, I have looked at those, and I don't like them -- I need a one gallon tank, not 5. And the one gallon metal versions have problems. They have funnels which are awkward, and then after use the funnel is wet with gas.

    The Calif certified plastic cans have integral spring loaded spouts that rotate out of the way when you are done filling. It never drips at all. All of the gardeners in my area (and there are a lot of them) use a model similar to the one I use.

    But your question raises an important point -- how in the world do most folks transport generator gas? What kind of can, and where to put the can? Maybe there is a really good solution that I am missing?

    I think I will start a "survey" thread. I guess on the Tech forum?
  • 5 gallons is too much for us, too. The steel safety can we carry in an outside storage compartment in our small Class C is actually a 2 gallon version similar to this one:

    The little 650 watt Honda we use for additional drycamp battery charging options carries 0.51 gallons and will run for 5-6 hours on that. Leaving home with a full Honda tank and with two gallons in the steel safety gas can, we are set up for five 5-6 hour running sessions with the portable generator.

    What we wind up with is three noise level choices for non-solar battery charging. Loudest is the built-in Onan, next quietest is the Honda, and quietest is idling of the main engine.

    Probably the Tech forum would be best for RV gasoline transportation information.
  • As I was driving to a welcome to the new year and new regulations meeting yesterday and following a tanker truck I couldn't help but think of this thread and how happy I was that I did not see your small gas can in front of me:):):):):).

    In the meeting they discussed portable fuel containers and one item was to start phasing out portable metal fuel containers. The thought process is a metal fuel can may cause sparks when it bounces on the road surface whereas a plastic container would not cause sparks.

    So ... a dispensing-safety compliant plastic container that bounces on the road surface and bursts to spread loose gasoline all over everything close by to be ignited by whatever ... is more safe than an overall-safety compliant steel container that bounces on the road surface and does not burst but maybe makes a spark when there is no loose gasoline around?

    I'll place my bet on the steel safety certifed can ... but of course high-quality safety does not come cheap. :)
  • Looks dangerous. Those fuel containers will not survive an accident. Look at something like a Rotopax container and mount it/them in a safer location.
