The first thing to look at might be widening the bunk supports. That increases the surface area and reduces point loads. At the same time, you might look at extending them towards the rear, if there is space. The goal would be to extend the bunks so that they support as much of a the flat areas of the rear half of the hull as is feasible.
Some people use a center bunk (instead of rollers) to support the centerline "V" part of the hull. Again, to spread out the loads.
A disadvantage of the DSII over the DS1 is perhaps the fact that the seat uprights don't connect to the hull and therefore don't act as stiffeners in the same way. Still, a wider support base should help with spreading the load.
Some trailers, as delivered, have criminally narrow bunks; those will eventually damage your hull.
If your bunk supports are nearly 40" apart, that's over half of the DS's beam (and the usable width for support is less, due to the hull's curvature). If you fit bunk boards of 8" or even 12" wide, that should make a big difference.
As far as rollers go, I would set things up so that the bunks are a bit higher in the rear so that the last roller in contact with the hull is no further aft than the aft edge of the CB trunk. Even if a bit lower, those rear rollers will support the front of the boat as it rolls on/off. Only when you fully pull the boat onto the trailer would the bunks take the full weight.
