Hi Jaap.
Unless you really want/need a ute, and if you already own a 200 series Landcruiser, why not upgrade your current vehicle to suit. Many 200 series owners, including us, have gone down the path of getting the Lovell Springs upgrade to a 3800kg GVM and a braked towing capacity (BTC) of 4000kg.
We also went down the path of considering an Silverado or GMC. However, our vehicle is our 'daily drive' so, since we live in suburbia, the 200 series Landcruiser was our best option because it's more user friendly around the city. If we were full time on the road, we would have chosen the Silverado or GMC; it's all a compromise to what suits your needs.
There is plenty of assessable information on this subject on this and other forums to research, so I will not go into the details here.
Cheers
Peter
