fullsize setup suggestions

im trying to get some ideas of what kind of setup i should run for my f150. im not too sure on how big i should go being its a fullsize. like what size line tank valves bags etc. i was thinking of Parallel/panhard in the rear with a basic above axel bag setup. or should i go cantilever? i could use some suggestions on that too.

its gonna be my first setup and i just want something thats pretty simple and should be decently reliable

any input is appreciated
