Hello, i'm having an annyoing issue with my 2006 (new shape) L200. When i get to about 65 mph i start to hear a really loud vibration, and when i get to 70 it feels like the truck is about to take off! Wing mirrors and rear view mirror are shaking and everything. Feels like it's coming from the drivers side front wheel, but i've had new bearings, ball joints (upper and lower), brade pads and disks, prop shaft ujoints, and tracking done 3 times, which hasn't got rid of it. Standard fit tyres. Any idea of what it could be?

try swapping your wheels front to back or left to right
I had a noise from mine a year or two ago and after new discs,pads and checking all the UJs/props etc , turned out to be the wheels themselves
not saying this is the case with yours but certainly worth checking just to rule them out

you haven't mentioned tyre balancing in the things you've done. It could be a simple thing like a balance weight falling off.
