I would like to run something by you guys. I have an idea to replace the two 30 gal. propane tanks on the tongue of my trailer, which I never use, with two military style gerry cans in a vented box for extra gasoline so I don't have to stop so often for fuel. The propane tanks when full weigh around 55 lb each. The gas cans would weigh a little under 40 lb each. Now I know some of you alarmists are going to shout danger and death at me, but I appeal to the innovative thinkers, designers, and off-road techies for your ideas and thoughts. I pull a 20 ft TT with a 2007 Toyota FJ Cruiser. It does a good job, but sucks gas like there's no tomorrow. An installed auxilliary fuel tank would make some service points inaccessable, so I decided against that. I thought this idea would be a viable alternative. So any input would be appreciated.:B

I see no reason why not.If you really want to be creative, just put a gasoline filler cap onto the propane tanks and fill them. Pump in a little nitrogen and then you can easily dispense the fuel. ;)

Three thoughts come to mind.......First, you never cook, use the fridge except off shore power or use the water heater?Second, a commercial gas pump moves fuel at a very high flow rate, IMHO pouring or pumping from a 5 gal. can will get old FAST. you won't be saving much if any time in the long run. Thirdly, if the FJ is that hard on fuel is an extra 10 gallons really going to make a difference?

I can imagine filling from cans if I was a long way from a gas station in a fuel thirsty rig with a small tank!! Pushing an FJ and trailer is what I can't imagine.

TT is all electric everything. We never dry camp. My wife doesn't like it. We cook with fire, a microwave, or Mr. Foreman.***When the idiot light on the dash comes on you need to find gas within 20-25 miles...period. Sometimes it ain't that easy.
