Installed a Redarc Tow Pro Elite V3 over the weekend as I'm picking up a new camper trailer next Saturday.
The unit is mounted on a bracket under the steering wheel. and the switch I put on the dash above the speaker.
The install is easy but Redarc tell you that it will self calibrate as you drive without a trailer. What they don't tell you is that without a trailer, there is no indication that it has calibrated so here I am doing laps around the block waiting for the LEDs to indicate is done. After wasting fuel, I got on Youtube and it's there the Redarc tell you it won't indicate without a braked trailer attached.
I wasn't happy that Redarc has upped the price to $350 over the V2 but it had to be done.
