I've seen rigs carrying "portable runway" sections like were used in WWII . About 18" wide and about 10' long with holes in them. Many would hook together to form a temporary landing strip. I don't know where you could get them tho.
Those "bridging ladders" are cool. Looks like lightweight but strong.
I know like 3 people that have tons of the portable runway sections and for the right price you could have some of your own.
