For a 30a trailer I'd suggest you carry a 50 male to 30 female and a 15a male to 30a female dog-bone. Also a 30ft or more 20a extension cord for those times 30a just isn't enough.. When we had our TT with 30a service I often had to use the extension cord for the electric griddle and breakfast.. as it would throw the 15a breaker in the trailer..
