Visible crew/equipment: When Dusty is showing off the new improved sensors, he is twisting one with his hand. The camera is blatantly visible reflected in it.
Continuity mistake: When the steak gets placed on Melissa's plate the 1st time at Aunt Megs, it is well done and pointing in 1 direction. When Dusty slips it's a totally different steak pointing in the opposite direction.
Continuity mistake: When Bill and Jo are driving up the hill, there is a shot of Jo driving, and you can see the windshield is already cracked. In the next shot when the debris of that jumper tornado is shown the windshield is perfect.
Continuity mistake: After the chase where Jo loses her truck, her pants are wet and muddy. After the flying cow waterspouts, the pants are clean and dry.
Visible crew/equipment: When Helen's storm chasing crew begins to take shelter in the building, there is a shot of everyone running down the stairs to the basement. This shot shows Preacher run into something. It looks like a hand-held camera.
Visible crew/equipment: When Jo and Bill are driving through destroyed Wakita, Jo looks at a family hugging on the side of the road. As the camera pans along them, the shadow of a boom mike is visible, gliding along them.
Continuity mistake: When Bill and Jo are in the truck, Jo looks at the dashboard, which is shown, and then Jo looks away and covers her eyes. Bill then floors the gas, and the dashboard is shown, and this time, the airbag light is on, unlike the previous shot of the dashboard two seconds earlier.
Continuity mistake: During a scene in the middle they drive the red Dodge solo into the hills to face a twister. As they bail out they find that they can't free the "Dorothy" from the back of the truck, so they have to run for it. As they look back they watch power poles start blowing up. Finally the one next to the truck goes and falls across the bed of the truck, smashing Dorothy onto the roadway and spilling the sensors. As they come back to the truck, because the twister has disappeared, they realise the twister is "jumping" and pile into the truck for their escape. The power pole is no longer resting across the truck and there is no damage to the bed.
Chosen answer: I imagine they just left it at the house where they loaded the Dorothys. You only need a couple of wrenches to remove a camper top.

They were not at a house.
