I have a 19" Phillips in my Camper, I found longer mounting bolts and shimmed the back of the TV out using the upper mounting bolts with washers(using rubber stem washers as buffers to prevent scratching) and it helped alot...
Yes, I fiddled with that. Got concerned because by the time it inclined enough to make a difference, I had little faith that it would safely travel down the road that way.
I was budgeting $400-$600 in late April for this. Might have to squeeze that piggy bank a bit more, much to the displeasure of my wife.
