Mission Trailers. Long story short, I had to sue the dealer because he didn't make the trailer to my specs despite having a specific contract. Horrible experience. They cost me some money. If you get a custom ordered trailer, don't expect it to be done correctly because it probably won't be right. Then if it is wrong, you will have a heck of a time fighting them. Lots of horror stories on that subject, but beyond the scope of this thread.
I think the reason people don't "see" me is because of inattentional blindness. Just like when people can't "see" a motorcycle or a bus on the road even if it is right in front of them. People expect to see a car and little else.
With my trailer people are expecting AC units sticking out of the top, maybe slide outs, pin strip swirls on the side, the door in the side instead of in the nose, crap strewn about, etc. And the cargo trailer part, I think they expect a polar white color. When none of those things match up, they have a hard time "seeing" what is right in front of them. It's obvious someone lives in here. I don't have a neon sign or an inflatable arm-flailing guy out front, but it is still obvious. Maybe not at a glance, but looking for the camp host? Totally obvious. But it isn't for a lot of people. Seems weird to me.
