The movie focuses on them needing a robot to transport water, but the main character is later seen driving around in a pickup truck much larger than the robot.
The robot, and the donkey before it, was apparently needed to reach camps in the mountains where vehicles couldn't go, and they were transporting alcohol and supplies, not water.

After Ernest shoots the first of the two water thieves, he pumps his shotgun but no spent shell is ejected.
During his fight with the camp foreman Ernest falls on his shotgun and it discharges. Shotguns will not fire simply by falling on them.
To prevent a determined Mary from leaving the house Ernest nails her window shut, but she could have simply removed the nails as he left the hammer next to the window.
Jerome (and the donkey) are startled when Earnest shoots the second water thief at the beginning. They're all located in a vast plain and Jerome isn't far from Earnest. It's hard to believe Jerome wasn't transfixed on his father in a firearm confrontation within shouting distance.
