If you are a group of tourists on your own self drive tour it is possible to enter Tanzania and visit the parks with a Kenyan registered vehicle. If you are a Kenyan tour operator carrying tourists, you run the risk of being stopped at any point and refused entry or hassled.
Remember that the Bologonja border post between the Serengeti and the Masai Mara is closed to foreigners. You can pass through Namanga, or the Tarime-Isabania borders.
You need to pay for Car Insurance for Tanzania, and your road tax for a foreign vehicle which used to be only payable in US $$, but now the East African Community is in force, I think you can pay the East African rate in Tshs. The same goes for park fees for the vehicle. This used to be payable only in US $$ for a foreign vehicle and cost a lot more, but now it should be less and payable in Tshs. Unfortunately sometimes the guys at the gates do not know the East African Community regulations and may charge Foreign fees for Kenyan vehicles. As long as you dont mind paying the foreign fees in US $$ for the vehicle as well, you should have no problems visiting parks in Tanzania with a Kenyan vehicle.
