x2. All of a sudden we had dishes falling out of cupboards this summer and then I discovered some small cracks in the frame due to insufficient cross members between the axles. This was causing all types of swaying and axle movement that I didn't really notice because it happened slowly over time as the few cross members that were there started to let go. It is now reinforced properly and rides better than it ever has.
