It would be nice if all screwdriver heads had corresponding colours like Robertson does, for a quick find in the toolbox.
#0 (yellow) - used for very small screws #0-4
#1 (green) - second most common, used for #5-6 screws
#2 (red) - by far the most common, used for #8-10 screws
#3 (black) - used for large screws, #12 or larger
Having the #1 & 2 (green & red) Robertson drivers will do about 95% of the screw heads. This is all I carry when pulling the trailer. Very rare to use the other two.
I am generally not a fan of multi-bit screwdrivers, though there is merit in having one for compactness with travelling. Do make certain you don't go for price when getting one. Spend the money on a good one, like this Klein model. You can always carry extra bits or nut driver heads to use with it.
