Also add that the trailer cannot exceed 750 kgs so its small trailers only,
Yep, small trailers and flat beds only pretty much!
I have a new style linscene which only allows me to pull 750kilo but you can't exceed 3.5ton so with the weight of the rangie I can tow 600kilo I'm now in the process of doing the trailer test which will then allow me to tow the max weight of vehicle and trailer combine which is like 6.2tonne
Yep, and its bl00dy expensive too FWIW! £300 minimum I think?
