I've swapped out the hydrogen tanks for large cargo containers

Hi Merii, will keep that in mind for the next Gas Storage Trailers, thanks

Since the hydrogen changes made this actually viable (yay!) this is such a good concept. One thing: it'd be a great generator trailer with more engines - a single O2 gen can support a pair of Small engines post-h2 upgrades (while Large is 1:1) and 2 engines can run nearly 3 hours off of the tanks on this and provide 1 MW of power.
