I built a fuel trailer with a 55 gal DOT approved gasoline tank and that works very nicely. Before that, I kept a scaffold in the hanger and built a small platform on it roughly 16" above the wing and could siphon in a 5 gallon tank in under 90 seconds with a $8 harbor freight 3/4 shaker siphon. That worked well, but it was hard to top off tanks completely and filling up cans wasn't as convenient as a one big tank - although much cheaper. That is a great way to go if you don't want to spend $$$$ on trailer & tank. Airport would have a hard time hassling you about having a 6' scaffold in the hanger and you can bring fuel to the field as you need it in cans if you don't leave them there.
When I was looking for ethanol free unleaded the local fuel distributor told me 93 with ethanol starts out as 91 before the ethanol is added and will return to 91 eventually if all the ethanol dissipates. That takes a long time in a sealed container. If in doubt run that in your car and buy new.
Lastly, because I avoid 100LL as much as possible, I sometimes carry 2 empty 5 gal cans in the tail of my CTLS and a siphon. I use a crew car and fill them up. I set them on a towel on the wing and siphon them in (being tall helps). Empty the cans totally before hauling in the plane; vapor is much more dangerous (explosive) than liquid fuel. This is a bit of a hassle but I dislike using 100LL. 600hour gearbox inspection & cleanings and reducing TBO by 400 hours is a bigger hassle IMO.
