Well after returning home from a weekend in PA Dutch Country (at 4K miles) I noticed the front tires were starting to cup slightly. A call to the local freightliner dealer sent her to a med duty front end shop in Philly. After much grief of finding the correct specs for the 2010 model year, my suspicions were correct and the toe was out. Called Forest river and they told me they had other unit with same issue and would cover the costs under the guarantee.
Just another thing to keep a look out for....
