This question is for the guys that have box trucks: When you fill up your mowers, do you do it all with gas cans or is there a way to mount an external gas tank under the box so you can fill up? I'm considering buying one before the season starts and was going over all the pros and cons and this one has got me stumped. It will be a diesel so I couldn't tap into the trucks fuel supply and fill the mowers up. I don't want to unload all the equipment and gas up-that seems like a lot of wasted time and I don't want to fill up 4 or 5 gas cans and then go into the the box and fill up the mowers and then fill them up again for spare gas. That's too redundant to be effective. How do you guys do it. I did a search and the only thing I found was a guy that took a portable air tank and rigged it up for 2-stroke gas.
