while PWM may be a cheeper unit, walk right buy it. in ideal conditions a PWM wont have much less output than a MPPT , but we dont camp in ideal conditions, we dont aim our pannels most of the time, we try to park under trees which will cast shadows over parts of your pannels, this is where a MPPT controler shines and makes a large difference in your output to your batteries. I have 480 watts of pannels on my 5th wheel and I am going to upgrade it to a MPPT controler. does the other one work, yup but I notice the differences a bit of shading can make on the output from one area to another. I am also putting a 355 watt system on my truck camper I just got. That is being set up with a MPPT right from the start. they may cost an extra 50 bucks but its worth it.
