When I moved from MA to PA years ago they gave us a truck that rocked back and forth like that semi. I should have known something was wrong because in stepping off the truck at one point my foot went down into a gap where the back step/fender was supposed to be attached to the truck.
We had to go to another yard to have it replaced and it took a day to move all the stuff from one truck to the other.
When we got to Philadelphia they tried to charge us for the extra day. I threatened media coverage and they not only didn't charge us, they shaved some off the original price.
