The bed is like 4 bolts generally and then the gas neck. I couldn't imagine how much of a bitch it would be to notch your frame with the bed on That'd be irritating and too cramped for me, unless you're like 4'8".
and 2 guys, i would def undo the six bolts and the gas neck and its off, 15 mins top. that will cut down ur notchin time down by atleast an hour i bet, and ull be able to make sure everything is exactly square and parrelel
