We hired a Landcruiser from Sunworld for two weeks in January.
Car was enormous - a proper 9-seat safari vehicle with sunroof and safari hatch. Car was very well maintained and reliable, but is not modern, e.g. no air-conditioning. In a place like Kenya that's a good thing, as there's less parts to break.
Included was an extensive set of camping and cooking equipment - basically everything you need to be comfortable. Only warning is to leave the Kerosene lanterns in Nairobi - they spill on bumpy roads and make quite a mess. The included electric lanterns are more than sufficient.
Some minor damage to the back (my fault) was treated professionally on return - no attempt at overcharging and it was all resolved quickly and smoothly.
