My trailer for my 272 has bunks. However, the position and adjustment of the bunks is important, just like the stands. The forward is under the bow.
The first pair of stands are under the forward bulkhead.
The next pair is at the midpoint.
The next pair is at the aft bulkhead (forward end of cockpit)
The last pair is under the cockpit.
If any of the pads that are not under bulkheads is too high, it will oilcan the hull.
Here is a picture:
