I'm probably one of the few who still does this, but it's cheap and quick. I use the green 6 gal jugs with the spout. I carry five of them and fill them when I get to the campground. Pull the vent plug out and tip the tapered spout in the fill hole. It empties in about 45 seconds or less. Yes, they're heavy, so not for everyone.
That's what I did and I always carry one of the cheap 4' step ladders and use that to rest the jug on while transfering so I don't have to hold the jug up to the spout.
For the OP 40 gal should last a lot longer than 2 days and IMO some water conservation training is called for in any event.
