I need to find some of those discussions because i really see no disadvantage to it...but thats also why I'm asking questions.
You see no disadvantage where other people have pointed out several, but that's OK. If you are willing to put up with something that others are not, it is not the disadvantage to you that it is to them. They don't log, you don't mind logging, disadvantage to them, not to you. They don't like the idea of hooking and unhooking a camper, you don't mind. Disadvantage to them, not to you.
But there comes a point where other people are affected by your decision and toting a camper behind your cargo van involves more than what you are willing to put up with.
Logging involves your carrier and the people in the safety department who are legally obligated to check them. Your choice to log burdens them with obligations that they did not choose to take on. For that reason, a carrier may prohibit your good idea. You may find yourself running under your own authority if you remain committed to your camper.
Many shippers would be surprised the first time you showed up with a camper and asked to drop it on their property while you are making a delivery or pick up. I can see someone on the docks saying, "sure, no problem." But when someone else drives in to work or looks out the office window, he or she will say, "What the hell is that?" The knee-jerk reaction will be to put no thought at all into inventing liability and insurance issues to justify a new rule prohibiting campers in the parking lot if no such rule exists already.
I would think that trailer hitch or wheel locks exist that would discourage theft of a camper that is parked on the street for the short time you are loading or unloading, but I would also think that it is illegal in many cities to park a camper on the street that is not attached to the tow vehicle. So, while it is no problem for you to drop and hook your camper on the street, the local residents and police may have a problem.
I like the idea and I especially like the pesistence you have shown in breaking new ground with an idea others have dismissed. Many new ideas are rejected by others before they are proven to be a success. It has been fun reading your determined yet respectful responses to those who poo-pooh your idea.
That said, I also like it when expediters are seen as a welcome resource by shippers, consignees and the public at large. Dropping a camper and leaving it unattended on private property or on a public street works against that. It gives other people a negative situation to deal with that they would otherwise not have.
