Did your try and Hinge2.

You can try with an Hinge between the deck and the truck and another 
hinge between the truck and the wheels
for the front and the back

The first Hinge should have and angle different than 90deg   w.r.t the deck
Ex)
Back                                               Front
-------------------------------------------
    \                                                        /
      \                                                    /


with this the deck should lean when you shift the wheight on the deck.
The fun part will be to adjust the parameter of the hinge.
