Here is what all my (now former) neighbors and I did. (Don't live there anymore, they do).
Take your big tank and set it in place. If you can put it underground, do. (You will be much happier with it underground.) Put it on the south side of the house. If you can't put it underground, then buy a green or black one so you won't have a lot of algae. Plumb it to the house (camper, shed, whatever) and use a 12v rv pump. Don't put the pump down in the hole. It needs to be in the house. You can buy the tank at a farm supply or coop in NM.
At the farm supply buy a 200 or 400 gal tank depending on what you will be using to haul the water. It will fit in the back of your pickup. If you are driving something else that can tow but doesn't have room in it for the tank then get a flatbed trailer for it.
Water can be purchased from most towns thru the municiple water dept. Call them and ask what you have to do. One place I lived you just fed quarters into a slot and the water shot out of a large hose with a lot of force. The next place you had to set up an account with the town and use a plastic 'credit' card that slid thru a reader. Then they billed you. You can be sure that there are lots of people hauling their own water out there.
Hope this helps
