Daf xf 95 480

Sorry to hi jack the thread, but it is relevant.

I hear the dads have head problems? And a lot you do see for sale have been recently rebuilt. Some at as low as 3-400k.

My question is are they a solid choice? And what causes the head problems?

We will be looking for something to move cabins and some plant so will probably be looking for something around the 500hp range.
