First work out *all* of the things that will have 120V going to them. This includes stuff like outlets in the kitchen and power for an outdoor grill. It also may include power to the furnace and to the hot water heater.
Once you have a good idea of how many circuits / how many amps per circuit you can go shopping for a breaker box. It's going to have to get tucked in somewhere. It will have a main breaker for the feed from the power inlet socket and sub breakers for each of the circuits. It may well have a few "ground fault" breakers in the mix.
The normal "big decision" is 30A or 50A feed to the box. A 30A feed is going to be 30A at 120V. A 50 A feed is 100A at 120V. There are multiple "standard" plugs for each of them. You can use the fancy Smart Plug's on either or the more traditional twist locks.
The key is to get a pretty good idea of what's what before you start pulling wire.
To answer the conduit question, the typical modern AS trailer does not have any conduit in it. There is a lot of debate about the "best" way to do wire in a trailer.
Yes, there's a lot more to it than this quick snapshot. There also are a lot of threads on this stuff. There's also no shame in getting a pro involved.
