This might not apply or be too late for you, but I had a 2008 JayFeather 25F and there was a recall on mine and some other models. The wrong axles were put on at the factory, when we would hit a bump the tires would rub the top of the wheel wells.
The axles were replaced under warranty, and it was at least four inches higher when got it back.....
