Hm, for what purpose?
Weddings: an easy 60lbs... the more primes I get, the heavier it seems to become! Although I only carry two bodies + lenses at a time, most of it gets used.
Portraits: maybe 10lbs - two cameras, two or three lenses
Wildlife: at least 35lbs - 20 of it in the 400/2.8
Landscapes: around 15lbs, including tripod (one camera, one or two lenses, accessories)
Lifestyle / sports: probably around 90lbs - includes everything from wedding stuff, plus the two big teles (300 & 400), not counting support & stands
It usually takes me two trips to get it to the car when going all-out: TT roller, TT backpack, TT laptop bag, two TT tripod bags
And add in one duffel of climbing / alpine / outdoor gear at another 40-50lbs and you've got a trunkful!
