Solar conundrum (updated with shopping list)

Ok so if you haven't noticed I am planning on a solar upgrade to my Sundance (See sig). I am going to be going with two Trojan T-105 6v's (225 amp-hours total). We just went camping and over the two days we used approximately 75 amp-hours, so lets say averaging 40 amp-hours a day.

I plan on installing a Bogart Engineering Trimetric battery monitor to keep an eye on everything.

I have been researching and Arizona Wind and Sun has some packages that I think I am going to go with. I have about $2000 budget for all. There are two kits that have caught my eye:

420 watt kit - $1545 shipped

320 watt kit - $1200 shipped

The shipped prices are for the kits only. The battery monitor, batteries, etc would be on top of that. Other than the obvious 100 watt difference, the main difference is the 420 kit has three smaller Kyocera panels and can be shipped for $100 via UPS where the 320 kit has one large Kyocera panel and has to be shipped freight to the tune of $225.

Is the smaller panels and 100 watt gain worth the $300? Would one large panel be the better option? At 65 lbs is it too heavy? Is 320 watts going to be enough assuming a typical So Cal. sunny day? Thoughts.......advice????
