Yes, you can wire it like a house. The exception will be any 12v dc wiring you do. Some rv/marine inverters handle the ground differently and you would want to follow the manufacturer's instructions for your inverter for grounding. You will also probably want to install an transfer switch upstream of the main panel so you can switch between your inverter and shore/generator power.
Your system design will depend on where your power will come from:
--generator (ac)
--shore power (ac)
--coach alternator (dc)
--solar (dc)
you can use converters/inverters to get dc from ac and vice versa
Design will depend on whether you will spend most of the time on the road, camped with shore power, or relying on generator/solar.
After calculating your daily electrical needs you can size your storage, (batteries) and generator.
If you plan to wire for 30 amp rv service you will have a main that is 120v only. If you plan to use 50 amp service it will be a 240v main and you will have two 120v legs. If you end up in a campground with only 30 amp service you'll need an adapter and no 240v devices will work because your adapter will feed the same 120v leg to both sides of your panel.
