Thanks Graeme.
Just a few comments.
Yes, but I don't quite understand that.
My understanding is that when the LR D4 knows its towing, its height settings will not go into extreme mode. I think ...
I read about an owner of a Vista RV off road pop top single axle trailer/van, they cost around $60k new all up, who when going through a creek up North, had this Disco go into extreme mode as the Disco's back dipped into a deep spot in the creek. The rear of the van was entering the creek, and when the back of the Disco went out of "hole" in the creek, the tow bar went to a great height - somewhat due to the extreme mode being very high. Which smashed the rear of the van into the creek bank. Unfortunately the back of the van hit severely and so badly damaged the rear of his van ... that insurance wrote of the Vista RV and bought him a new one.
Evidently if the Disco had known it was towing, and that there was a van behind, the Disco would not have gone into extreme mode ... that's my understanding, anyway, from those discussing towing recognition elsewhere at this site.
That's logical because most towing is done on bitumen. Being level is extremely important with a twin axle trailer of course. But not so critical with a single axle.
I read an advertisement for someone who said he was selling his caravan because he had problems bending down ... attaching the chain coupling was a big issue, and raising the front of the van in order to attach it to the tow bar was a major drama for him.
Your devise allows one to lower and raise the car, from access height to extreme height - a huge variance, which IMO should be a major marketing benefit for Land Rover towers. Instead of cranking the front of the van up and down to attach to the Land Rover, with Llams you can just adjust the height of the vehicle for an easy coupling or detachment.
With my D4, if you put the hazard warning lights on, you can lower and raise the land rover, from outside the vehicle. How does your system work with that? On the key Fob, there are two buttons you push, and the vehicle goes from access height to the vehicle's height setting. I presume that if your set Llams to extreme height setting, then you could - using the key FOB - go from access height all the way to extreme height ... if you stop pushing the button on the key FOB, the vehicle stops going up (or down).
Could you advise who? Melbourne has 4 million people and quite a few Discos, plus some great areas to tow to and also to off road. Sometimes a neat job done by someone high on the learning curve is money well spent.
