The OP posed a number of unrelated questions right from the start, which made this thread both interesting, but also confusing. Changing his lifestyle, work, etc. His expectations of getting a clear and singular recipe for what TT to tow with what TV from this group, or any other, were unrealistic. We all have different likes and dislikes, expectations and needs. When it comes to towing within specifications - how much margin do we need to feel safe? 1% or 50%? Can we go ten pounds over? I just re-read this thread and I do not see that Casey was driven away. He simply better get more information from car manufacturers and other sources and ruminate for a while before he makes his move. (And maybe have drink with that lady?)
If everybody had the same opinion on everything, life would be so boring.
