Hi Bill,
Don't listen to the nea sayers....When I built my 280 watt system I was told by a bunch of folks on here that my wire was wrong, I need to tilt them, my panels were too expensive , 12V panels were a waste of time...I should use a different controller, my batteries were wrong and I used the wrong size circuit breakers.....All from the worlds leading authorities...
But as you saw this weekend. I went four days...and two at a nearby campground before the meet, with two of the 6 days pouring rain, and I never ran my generator once!!! I made 4-6 cups of coffee a day....watched a 2+ hour movie every night....used my laptop/cell booster/wifi booster until my fingers bled....charging the laptop, the hot spot and bunch of folks cell phones.....ran the 12V compressor every evening to clean the guns...ran the water pump often for dishes and a shower every day....AND NEVER UNPACKED THE GENERATORS!
I saw your system putting out some good numbers when the sun was shining. I'm sure you'll be happy with the performance you will see and you can always add to it later for more "juice" if needed...
As far as price....some folks on here are so cheap they would run retreads on their trailers. And others spend $50K -$100K for a POS travel trailer with all the usual RV QC issues and complain about a few hundred dollars for well built, quality accessory.....
The internet can be a nasty place. Manners are not needed when not face to face.....:B
