For a daily, it's hard to beat PS as your base, unless you want to venture into coatings. Like Tex said, HGG every 3-5 washes or so is perfect...and certainly not excessive. These two products alone will give you solid protection, beading, and shine through the winter months.
Ading waxes will give you more depth/shine, but on a white car/truck, not as much as you'd likely see on a darker colored car. The HGG, on the other hand, works like a champ.
