teardrop trailer wiring

i was wondering if anyone had done any rv wiring? i would like to know how to wire for campground 30 amp plug in and also to run a generator. i will be running a microwave and a low profile duotherm unit (to keep the wife happy). my question is what will run off of ac and what will run off of dc? i have little to no experience with wiring and need all the help i can get :thumbup:.
