Horrible tire wear in 2 years

Well just to update. I finally got my trailer into an axle shop this spring. On Friday I got the dreaded news, I need new axles, they're so bad they won't even let me drive it off the lot without fixing or having someone tow it. Exact quote from the mechanic "these axles should NEVER have been put on a trailer of this size". Forest River has not responded to emails or voicemails since last fall so they for sure aren't going to address this issue. Just sucks to have axle issues within 2 years of spending 20 grand on a new trailer only to find out that no matter what I did that I would have axle problems. We only go for weekend trips, so just clothes, food in the fridge, coleman grill, and fold up chairs are what we travel with, no way that should overload it.
My last hope is the dealer, they're calling me tomorrow to discuss.
