baggin a d50

i just wanted to know how big of a notch does a d50 need to lay frame? is a 6'' too small? also anyone with a bagged d50 could post pics of there bed setup cuz im tryin to figure out how to do my bed layout. i was thinkin of puttin my air tanks on the sides of the front of the bed, each compressor by each tank and a fuel cell in the middle
