Yes it's sways sometimes, bit of a worry. My hubby says to keep the weight towards the front which we try to do, but now he is saying we shouldn't fill the jerry cans as it makes more weight on the back. I worry as you see so many accidents, and also some of those big vans sway real bad. Our van is only 14' long it has 2 single beds at the back of it and then we have a pull out kitchen/fridge etc, the front of the van folds out to a queen size bed. When we travel we put plastic bins, annex, table etc in the walkways we have 2 batteries which are under the beds. We usually drive at a reasonable speed, as it is a concern with the swaying. Any suggestions
