Semi-Trailer Weight Distribution

I am writing software for weight loading/distribution in a semi trailer.

The current trailer model has two points at which it is supported. A fixed fulcrum approximately 2 feet from the front(I would prefer it be variable for future reference) and a second point near the rear (adjustable from 0-72 inches).

It is my intent for the loading software to be able to provide the given weight for each linear inch of the 53 foot trailer. Any assistance in acquiring or deriving the formula(s) needed to calculate the load on each of the two fulcrum points in the image below would be greatly appreciated.
