Statistics about trailers and it's specific profit

Hey all,

some of you ask yourself which trailer to buy, which has the best profit margin possibility. So I did some extraction of the files on myself and as there were some hours of work maybe some of you find it useful. So I am sharing the statistics with you. First step are fuel, chem and gas trailers as it is a bit more difficult with box trailers but will follow soon if interest is given. So comment and rate and give improvement comments what you wish to know!
First of all an overall overview for specific trailer and it's length and type:

And here are the states of US without Nebrasca as I need to get and add it but this might follow soon if interested:

States with red square only allow single and double trailers, with a green square only allow specific special trailers with it's description what is forbitten written down. Full green square allow anything.

Let me know in the comments if I should expand it further for you or nor or where I have any errors.

So as a conclution: you have to map and look into what your cities are exporting and importing. Next you see chem trailers are the least profitable ones. I suggest gas trailers or fuel trailers. Gas might seem the best as you get most of a double trailer out of it which is allowed everywhere.
