Spring failure is not a common Bounder failure. Bounders are no more over loaded than any other brand. In fact spring failure on the OP's coach would be almost non existent, as the OP's coach has a tag axle. Thus giving the coach 20 or 21 thousand pounds GVW
To the OP, two of the best thing you can do to make your coach drive better is 1: get the toe in set to 5/32" toe in and 2: add a front track bar (pan hard bar).
