By the time we traveled through British Columbia, Montana, Wyoming and Colorado to our home in Nebraska, the crack had lengthened to nearly 12 inches and we began noticing cracks to start on the four corners of each of the slides. We made an appointment for it to be checked and dropped it off for a two-week inspection. The dealer found that the cracking was not only on the outside, but also the inside. The axles and leaves of the axles were flattened not allowing for the correct suspension and so with every bump on the highway – and Alberta, Wyoming and Colorado are worse than the Alcan – the entire trailer was being jolted.
