Camping equipment weighing 6000 N is pulled across a frozen lake by means of a horizontal rope. The coefficient of kinetic friction is 0.05. The work done by the campers in pulling the equipment 1000 m at constant velocity is:

We never utilized friction this chapter so I don't really know why this a problem on the homework but is it just W = 6000*.05*1000 = 3*10^5 J

Yes, that's it!
The (kinetic) friction coefficient times the weight is the friction force that must be applied.

Why do we not need to convert N into kg?
