I think - you need to reconsider your needs are wants. I always suggest to new T.T. users, a 24 foot long T.T., 1 roof air with heat strips,! bed for adults, 1 couch for youngsters that may be along, I have used this size all over our USA, Canada, Alaska, & Mexico,you can increase the size of your AC if you find you need it. 30 amps will serve your needs if you travel down south, in Mexico many parks only have 110 volts.And many it goes down to 90 volts at times.
Main thing is get something you can handle and go enjoy yourself.
