I know a few sparkies through work and so far they are not that keen on the Redarc unit.
Issues that 2 sparkies have advised below>>
1 The cord is not long enough so that unit can be placed out of the way under the dash away from the controller on all vehicles.
2 There is no adjustment on the gain like the P3 Teconsha B1,B2 and B3
Then I rang Redarc (Technical support) and asked them if the unit has a function like the Teconsha with the B1 through to B3.
Quote "you don't need to adjust the gain with the new Redarc unit because it does the adjusting automatically"
I would assume that every time you stop and start again the unit calibrates itself. How can it do this?
For example you have got to a destination and unloaded the van of all the water and beer, food, fire wood and so on.
Then you hop back in the car with caravan in tow and the unit is set up for a full load in the van and your now doing say 90kms, then a Roo jumps out is front of the car. Before you know it the gain is to high and then the caravan wheels are locking up due to the gain being too high. At least with the P3 can turn the gain down and to me that is a massive safety floor that the new Redarc unit does not have. I know that the Redarc unit can be calibrate before you set off before each trip but you cannot adjust the gain on the fly like the P3 /B1,B2,B3
I am not convinced at this stage that it's worth replacing the P3 but will be keen to hear from anyone else that has had both and can compare them that has done some towing with a caravan that is over 1800kgs and not just a camper trailer that is not really testing the unit out with the gain control.
