Be assured that no one is laughing at your misfortune. Unfortunately, stories such as yours seem to be becoming more and more prevalent. I'm sure we all have found your report to be educational.
I find it very interesting about the dealer not advising you that "someone" had "crashed" into your trailer while driving through their parking lot. I sense that you are just as upset as any of us would be if a dealer treated us in that manner. I do hope the damage was not serious.
What you have shared makes me wonder who is paying for the repair of the damages caused by the crash, and about the identity of the errant driver. I don't know about how things work in Texas, but where I live a driver who causes property damage is obligated under penalty of law to make their identity known. Have you asked the dealer to provide you, the owner and maybe the person who has the legal right to recover damages, with this information - if it is known to them? (There may be some concealed damages. What do you do then if you don't know who was responsible?) Likewise, if the damage was caused by a hit and run driver, was a police report was made? Was the dealership maybe concerned about some kind of liability issue? Gee, I can think of a whole bunch of questions I would like to have answered if I were in your place - if for no other reason than to put my mind at ease.
Good luck with getting your issues resolved.
Happy Camping! ///// Richard D.
