I also organise my lot
The drummer helps with logistics and planning etc,and is always there for load outs and ins,unlike the singer and guitarist but I;
Supply and drive the van,
Provide,assemble and operate the P.A, which consists of a Soundcraft SI 1 or 3, into a Bill Fitzmaurice DR250/Titan39 rig with qsc amps,and 4 stereo in ear systems, all mics, D.Is, cables and stands.( and (that's every rehearsal when it needs putting back together after a gig, and every gig after packing it away after a rehearsal,and that's if nothing needs fixing or replacing).
Supply, rig, and program the lights with my truss,par cans, scanners, smoke machine and small DMX desk.
Create and operate the backing tracks we use, using my Macbook/logic and iPad,in my studio.
Record and produce any promotional recordings we need.
Manage the band kitty and pay the bills on the rehearsal room, clean and organise the rehearsal room,
Manage the sub letting of the room to offset our outgoings and do DIY improvements like shelving curtains chairs, kitchen items , fridge and a microwave.
Pay for the web hosting for the website, manage the facebook and Northwestbands accounts. Run the online diary.
Oh yes, I play bass and sing as well.
And work as a freelance engineer.
My lot are lucky, as I operate a small hire company and they get the benefit because for me, it has to look and sound as good as possible, but I also keep telling them that turning up on time and playing their chosen instrument is the minimum they are expected to do, if they want to be part of a reasonably well run and profitable band.
So to the OP. don't tolerate laziness from your partners, otherwise you will end up carrying all the responsibilities,make no money and eventually end up destroying the band out of resentment.
