a small but quality highway rated open utility trailer would be my choice... I wish I had spent a couple hundred more for the wooden floor model...a hitch on my lawnmower made transporting the pre cut plywood and ladder easier to transport to the windows...a hitch carrier could also be used
select the same size gasoline containers, as it makes them easier to secure with a tie down strap... much larger than 5gal is awkward to handle
the plywood cut, painted, and numbered for the 2004 season was a lot easier to put up at 58, than at a month shy of 70....have a good quality drill/driver with a spare battery... torx or square head screws if you attach to frame
I may convert my non used 5cu ft. freezer to store and and on demand freeze gallon containers of water for my extended coolers..
don't overlook the need for extra 5 gal buckets with lids
