Try it out, figure out how everything works then decide if you need to change things. Couple of immediate things to have, leveling blocks ( I carry two ten packs 4 squares of 2x6 pads for under the jacks. spare batteries for the jack remote, a 2way level of some sort, pots and pans that are the correct size to fit the oven burners. And most importantly prepare to toss the stock mattress for something comfortable (best upgrade I made). But most of all don't let the fear of I haven't done this before stop you from doing or trying things. This, contrary to popular opinion is not rocket science, it is pure fun.
