thinking about building a bed

[mike in mo]

My crewcab came to me bedless and i don't want a factory bed. I been thinking of building my own bed it will have the slide in camper on it most of the time so it needs sides and to be some what like a stock box. Can some one give me some measurements from a bed like floor to top of wheel well ,wheel well to wheel well inside and floor to top of side. If any one has built something like this (I know i cant be the first guy) ill take any pics and info i can get. Thank you
