Do you plan on camping in less than perfect sunshine? In low overcast with flat 420W array you'll get about 30 AH. Less if there is a low overcast AND you are camped in partial shade.
You said you are using 70 AH overnight. Plus, unknown AH during a day. Say, 40 AH? 110 AH total. This means you are taking 80 AH from the battery on a dark day. Probably more, since the phrase "I am not one to conserve energy" normally means microwave, coffeemaker and God knows what other high-current draws, and those suck the energy out at faster rate than it "should". This is called Peukert effect. So if you don't do something about conserving energy, in low overcast your 450 AH bank will last 2.5 days or less before the charge drops to 50% and you have to run a generator.
