Wow...just read this thread and all I can start with is...Wow...
That is utter and complete BS from that company. From manufacturing, customer service and just plain service standpoints. If they had any kind of morals or heck even dignity as a company they would have refunded/replaced that trailer long ago.
Story time:
At one point in the past I was working for a small technology company (won't bother putting the name because most haven't heard of them anyway) who used and purchased about a dozen or so servers from Dell literally every month. I worked there as the server technician rebuilding these servers as needed.
Well, time went on and I noticed a trend in a specific hard drive model. It tended to go out more than the other brands they tended to send us as replacements. So I gathered up some data (meaning I put together a spreadsheet complete with charts and graphs) and contacted technical support at Dell. First level, obviously, did nothing. Second level tried to say I was installing them incorrectly (seriously?). By the time it was all said and done I had been through the tech support manager, the regional manager, the area manager, the CEO of tech support, the customer service CEO and finally Michael Dell himself (we had some great conversations...he's actually a pretty funny guy).
In the end not only did they stop sending out that particular drive, but they sent me four cases of a MUCH better brand of hard drives to replace the faulty ones as they came in.
Now THAT is how you do customer service. Granted I had to climb the corporate ladder but they made it right at a pretty large expense to themselves (not only the cases of hard drives themselves, but purchasing more expensive hard drives for not only their service department but their assembly lines as well).
This issue with the trailer was completely ridiculous. Not to mention how you were treated by their supposed customer service department. Personally I would still contact they news folks and get them to do a expose` to hopefully keep other people from getting ripped off.
