On general electrical advice - put in large enough panel to have PLENTY of 20amp breakers and have no more than 2 wall plugs per breaker!!! Overkill?? NO!! You will be glad you did when you and the wife start to plug in ALL the electrical stuff you will use. Better to have too much than not enough - hard to add later. Just saying....
PS: Get the Furrion inlet with the cord and handle adapter together.
It's easy for me to spend your money!!:B
I speak from experence. Built a 24x8 concession trailer. Had an electricion friend help me wire it. He "MADE" me put in larger panel than I thought I needed and more outlets. Turned out HE WAS RIGHT.
