What does a standard propane system look like?

I will probably have 3 propane appliances, and a single 100lb tank on the back.
Ive installed black cast iron gas pipe before in my house, but I dont know what I need for the hookup at the tank. 
Im seeing a lot like this picture below;  looks like flexible hose goes into a regulator mounted to the body, then inside the truck for distribution.
 

 
Then this one uses a copper pipe:
 
 
So:
1. Whats best to use between A and B?
2. What should I use between C and D.. Black cast iron?
3. Do I need a certain kind of regulator?
4. What size black pipe should I use?

    I used the yellow flexible hose, they sell it at Menards. Really easy to work with.

    The copper can work well.  It will flex ok for bumpy rides.  That is why the copper is looped.   But !!! it can pinch easily if the line was hit or pulled on.     ... Basically, just used the rubber or metal gas flex line for the connection.
     
    What is the total BTU usage of the appliances and each?    A 100lb tank produces 79,700 BTU/hr at 60 Deg F; more if warmer & less if colder.

    Griddle 140,000
    Steam Table 10,500
    Rice Cooker 35,000
    2 eye Burner 22,000
    Crepe griddle - 24,000
    total -  231,500
     
    Now Im wondering if even 2 x 100lb tanks will be enough. Yikes
    But it will be between 70-90 deg F

    Those are maximum BTU ratings, we hardly ever have the need to turn everything up like that.

    Ive done a little more reading but I still dont have a propane plan mapped out. 
    There are so many regulators and I dont know which one to get and what factors influence the choice. 
     
    1. Is there a way to calculate which regulator to use?
    2. should it be a single or dual stage one?
    3. Also what size supply pipe? I did use the rego app and I think I should be 1/2 inch.
     
    A local guy is using 1/2 inch rubber supply line from the tank to the primary regulator, then 3/4 inch to the 4 appliances, like this... not sure about going from 1/2 in to 3/4.

    That picture looks clean and legit. 1/2" is pretty big on the high pressure side , considering most are 3/8" out of the tank. The larger the black pipe the more gas is available , it is still the same pressure and acts like a storage area for your gas , I would use 1" black pipe and T off as needed. If you connect 2 3/8 lines you would need 3/4 inch BI pipe in theory, but I doubt any appliances would take a 3/8 id fitting unless you plan on using a Wok. Others here will chime in with " numbers and facts " I can only comment from experience.
