I feel like my cruisers and shaped boards I have set up skate better with wider trucks, but that is just me.
Sure the wheels stick out a bit, mainly more so at the back with the fish shaped cutout, but as the tail and shoulder of the deck are wider, they are proportionate.
Same as we skated back in the 80s, the back trucks always looked too wide and the front trucks always looked too narrow, while still being the same size set of trucks, but with trucks that were too narrow, the whole setup felt way less stable.
Personal preference does have a lot to do with it, but I have 159s on that size board and they skate really well.
