First up I am not an expert nor do i proport to be... however what they have told you is kinda wrong kinda right
wrong... they cant void your warranty based on the controller you use
wrong... it will work with your penguin
HOWEVER
the redarc is a solid state (or static if you like) controller and the Tekonsha is a proportional (or pendulum as they have called it)
this means that with the redarc.. when ever you hit the brakes (either tap the pedal or stand on it) the braking to the trailer will be the same
A proportional controller will vary the amount that it applies the brakes on the trailer acccording to how much the vehicle is slowing down.
For me, I prefer a proportional controller and I think they perform better. But that doesnt mean YOU have to have one, the Redarc will work fine (and probably look better)
by the way if you change your mind and want the tekonsha.. buy one on ebay it will be heaps cheaper than Jayco
