shifting camper

IIRC as you let the jacks down the tub of the camper tends to move away from you . I could have that backward but you'll know when you're doing it . So lift the camper so it's slightly off the bed then lower the side that needs to move away from you until it hits the bed , this should hold it in place while you lower the other side . It takes some playing around . The other thing to determine is why it shifter . Good luck

The only way I know of is to raise the camper and move your truck under it. The tie downs that bolt to the frame are best and most secure.
