This is from not coating the steel properly and a reaction pss poor trailer.
I find it extremely disappointing that this customer is so quick to blame faulty material and workmanship,while disreguarding any maintainence responsibilities he may have. It is very clear the corrosion issue is only around the fender box where the majority of road chemicals are distibuted. In addition, the exterior screws and cams are discolored, a clear sign of extended salt/chemical contact. (wash your trailer).

This customer's unit is also outside it's warranty period; however, to condemn a mfg. for offering to repair this unit free of charge, no matter how old the unit, providing the unit is repaired at the factory, is perplexing at best.
rsaint, your trailer is not an x-box (totally different unit)
If your intention is just to smear Mirage, that is well within you rights; however, Mirage stands behind all our products. Again, though your trailer is no longer covered under warranty, our offer still stands to address your issue at our facility, free of charge.
