I'm curious ? Here in Ohio if you have a 1 ton Van (such as my E 350 Ford Van) you are considered a commercial vehicle and required to purchase commercial license plates. This can create some issues with insurance companies who will insist on selling you insurance for a commercial carrier.
I was allowed to purchase (for $10 dollars less a year) House Vehicle license plates. Likewise my basic insurance for passenger vehicle. I've yet to be pulled over by a LEO and requested to open the Van for inspection.
While the notion of making some $$$ to haul (what we call "Hot Shot" service in my area) small important items that require PDQ service is attractive, most of those needing this service want an item to be in transit as soon as the driver hangs up and proceeds to the pick up point, loads, and then to the destination to deliver. There is big pay for this service but it assumes you will be headed out as soon as you hang up.
Will any of these Transport services be paying the Van owner in a way that reflects the value of his/her service ? (I guess what I'm saying is will you make money in a way that would allow you to replace or maintain your equipment ? Or would you be better off work camping and not wearing out your Van while making the other guy rich ?)
I can see how some would suggest this really isn't for nomads.
If someone had themselves licensed and insured commercial and kept books to log their mileage, fuel records etc to run this as a small business I could see them advertising their service via a website. (where they offer 24/7 service) I would imagine they would have road side service and towing insurance too. All of these things would have Tax advantages as cost of business. But then you are running a business and won't be enjoying much of a nomadic life.
If this begins to become mainstream, I'm sure LEO's may begin pulling the nomads over just to see if they are hauling in a less than legal manner. This most likely at the urging of freight companies who don't engage in this way of transport.
Just want to put some of these ideas out there to consider. I know it goes on all the time, but I'm sure those who get entangled with the Law would be made an example of.
