I mowed yards this year and outgrew my single axle 6x10ft trailer. I'm now going to get a double axle trailer and I'm going to put a trailer brake(s) on my new one. I'm a novice as far as knowledge on this, so I'd appreciate some help. I see that several people get the Prodigy digital brake controller. Is there a reason that this is more liked than others? Should I go with a cheaper controller or not? Please respond with feedback whether it's positive or negative for one controller vs. another. Also, do you advise that I get one brake or should I have brakes on both axles? Thanks.
