To the OP I hope to see you back, I can recall you among others in this thread having some informative posts. This site was really invaluable to me when I got into RV'ing and now it has helped me with several TV issues.
Lately I have also noticed the decorum going down lately but I guess it is just a sign of the times as people face more pressures/stress in their lives there has to be somewhere were they can vent. There is nothing wrong with disagreeing even if both sides "think" they have the facts. In the end we have to remember that most of us love this hobby/passion/lifestyle foremost and which brand vehicle, tire, or even diesel vs gas is just secondary banter. I hope I didn't step on anyone's toes.
