I had the problem with bandmembers that were too lazy to help with load in/load out. Thanks to the TBers who helped me out on this one. The solution was that bandmembers who don't help out get a smaller cut of the money form a gig, plain and simple.
I myself, get the lightest gear that I could get away with and aim to do load-in/out in one trip. On most nights I do. If there is a gig where I need to get in and out quick, or load in is a royal pain in the a$$, the stage/room is too small, I'll bring my Sansamp Bass DI and no amp. Since we have a decent PA and monitors, it's no problem for me. Since I'm the soundman, I can tweak to my desire.
