Are you serious? Maybe you should pay attention to the things you wrote.
1. It's not a fact. It's your opinion, "bud". Your statement was based on nothing but arrogance - you have no idea about his ability.
2. YOU SAID THIS "if you need to open the door to back up a trailer, you have no right hauling the trailer in the first place". Did I make something up or did you reference backing up a trailer?
3. Who was it directed to? You replied to his post. And yes...It was unsolicited. He asked for a work-around - not your advice on needing it or not.
You know what you are? An insecure little boy. It takes more of a man to say something like "yeah, that's funny...I guess you got me on that one". No...typical insecure a-hole who will argue in circles to avoid being wrong.
So tell me, "bud".....what did I "fail to understand"?
Let me guess....We'll hear silence.....Or will you keep sidestepping and going in circles?
