We could spend an entire week discussing this topic around the campfire. My wife and I get frustrated with the lack of knowledge and training of employees in so many fields, we wonder if anyone has pride in what they do anymore. But, a lot of that is probably due to bouncing from job-to-job, and that can likely be traced back to low wages, or bad compensation plans.
When it comes to talking weights and specifications to customers, I can tell you from first hand experience, most people don't want to know the truth - even if they ask the question. Yes, there are some out there that choose safety over features, but (IMHO) they are in the minority. When I was in sales, there were many times customers got irritated (almost hostile) when I shared the hard facts with them. There's probably many on the forum that have experienced this same thing in their field. It can be very frustrating. I think people that visit this forum are the type of folks that do research and care about such things. Others just go buy the first rv that has the desired flash.
I'm curious to hear your thoughts and experiences.
