MPPT controllers of decent quality are coming down in price to a point where there isn't any reason to bother with a PWM controller, especially on the limited space of some rigs where one needs every watt possible.
Shade will kill panel output, where even a little bit on one cell will cut the panel's output by 90%, so multiple panels avoiding shade is a wise thing.
Also, don't forget wire gauge, as almost all solar installations run too small a wires, and voltage drop can mean the difference between a good battery charge versus never getting near 100% SOC, especially the wire run between the charge controller and the battery bank.
