Car seat/travel systems

So we are due with baby #3 soon and would like to know what you recommend for a car seat and stroller. Our other two kids are old enough and walk everywhere so we don’t need a double stroller or anything but I don’t really know where to begin I really seem to like the graco brand car seats but I’m at a lost for what kind of stroller we want obviously I need something to keep up with my other two kids and we’re big on camping and going out places so something that does good on different kinds of surfaces would be great! Is there anything you like or recommend would even be interested in looking at different brands
