I have a variety:
At the house (primary use is for my B) I have a 25 gallon fuel caddy that I paid for in Cabela’s points. It’s ok, but it’s easier to take cans than load that up to take to get fuel. I also use a ac/dc/battery want for the pump. Just that alone with the cans would have been fine…it would have been better for me to buy extra Jerry cans than the fuel caddy for my use. So in this case the caddy was a waste of points…but I am able to have some extra fuel on hand…I don’t really need that much on hand though. Key point is the wand that pumps…when it craps out I’ll get another.
For the MX I have an HMC (it’s beautiful and made in America) fuel caddy. Not cheap but it’s built in USA. I use Jerry cans to keep it filled. It works great and is nice to have extra on hand. Mx is a bit thirstier than the B.
Ultimately I think extra Jerry cans and a wand is the economy option (compared to a caddy and easier to take to town). Unless you have the option to have fuel delivered or a transfer tank in the truck. Once you go to trouble to load a fuel caddy into the truck, it’s easier to deal with cans IMO. Anyway IMO I think a quality transfer tank in the back of the truck is the answer unless get fuel delivered to your farm. But each of the options comes at different usage quantity and different $$$ involved. Everyone’s MMV

I think it comes down to your rate of consumption. Take bourbon, let’s buy that by the barrel. Now milk, just fill my glass when I want some.
