sam,
pros:
instant rollbar
no worrys of breaking out rear glass while loading brush.
rebuildable\removable bedsides,
hidden 5th wheel if needed,
scratches easliy fixed,
bed floor rock solid,
taillights cheap to replace,
hang,hook,weld,tie down anything on it,

cons:
people love 'em or hate 'um for looks that is.
i just boughta new one for my 70 f250 4x4 and it's even got back up lights in the headache rack and a break light in the center.
i use this truck for work mostly but a can't justify a original bed.it would be like my original in no time.
also for anybody who remembers me braggin' about my truck for the last 7months,it has been torn clear down and getting totally gone through*****pt drivetrain.
i am knee deep in it.
sam,
my bed cost 1200$ but they come alot cheaper than that.people build 'em themselves to.
