I don't know what vehicle you tow with Highlander but be aware that the AlKo stabiliser handle will cause problems if you tow with a 4x4 with a rear door mounted spare wheel.
The handle fouls the spare wheel so you either have to do as I've done and remove the handle and slip it back over the forks to engage and disengage the stabiliser or buy an extended handle.
If your caravan is not already fitted with an AlKo stabiliser you may need to change the towball on your vehicle as well for a tow ball with an extended neck.
The AlKo 3004 is for caravans up to 3000kgs but to be honest the level of security offered by the AlKo hitch lock is marginal.
Don't depend on that alone to safeguard your caravan.
Apart from that the price is about right, it's about
Thats one of the reasons i put the winterhoff on was problems with the spare wheel on the back door, the van was seven years old and it was the original hitch, its now on the front of my trailer, so i made use of it, Trailer Trailer in use
parksy, i tow with a vectra. also, the deal is for the triple pack which includes the new towball. at the moment i have the other alko hitch ( is it the 1300) but i like the idea of the inbuilt stabilisers on the 3004 which takes away the need to couple and uncouple my blade type everytime i go.
