Any ideas what the laws are on transport?

While specifics vary as Ed posted, generally sotoo 20 gal is legal in
DOT-rated transport containers. It's a relatively low hazard but like
anything else, "stuff happens" and in high traffic areas or other
reasons for higher than normal accident probabilities one should be duly
aware.

OTOH, for farm use I keep a 150 gal diesel and 40 gal gasoline transport
tank in the pickup as we have done for 50 yrs or so. Compared to the
1500 gal anhydrous ammonia tank tagging along behind, the fuel risk is
quite benign...

As for the original question on storage, I'd try to make a shaded
location for the storage if you have no shed to minimize the chances of
lifting the safety relief on a hot day of a full can but other than that
I'd have no particular concern, either.
