Here ya go, what I been looking at:
https://colemans.com/shop/containers/medical-transport-chest-u-s-g-i-aluminum/
The extra large is 2-3 inches too tall but otherwise I think the Honda will fit, along with a gas can.
Or put a gas Wavian jerry can in a bracket, Amazon has them.
Or if you are using an IPI extended run gas tank, one of the more shallow surplus boxes would work for that.
Coleman has new/un-used for $20 more.
Or this one that is "out of stock":
