Thank you for a thread that draws attention to dangers of ignorance.
I think regardless of the make and quality, it is our responsibility as equipment owners to be aware of what we are driving and pulling, both motorized and not. Whether a horse trailer, a quad, a camper, a motorcycle, a truck, car, etc. etc. I see far too many people that have no clue whatsoever about their equipment. I can't number the amount of times I have gotten into a vehicle with someone and asked, "how long have you had that rattle in your right front wheel?" or something equally obvious (to me, anyway). How can someone pulling a car hauler not notice that one tire is just about completely flat? Or drive with only one headlight? Or not check the lights on their trailer before they pull out of the yard? Yet time and time again I see it.
We own it, we drive it, we are responsible for it. I have driven rust buckets, and trailers that aren't the best, but so far (knock on wood) I have never been surprised about any repair needed on any of my equipment. I KNOW what's there.
