I want to install batteries, solar and AC in a 95% restoration of a '62 shasta airflyte. Need pictures of existing systems. Trailer will have a 5,000 btu AC and would like to get the most energy possible for lights and accessories.

It will be really tricky to be mobile with enough surface area to pull enough amps for a 5,000 btu Air conditioner. On demand constant? Your battery storage will be huge! A swamp fan? not so bad and totally duable.. But in Florida, more wet stuff is the last thing you want. Like GK said, you can entertain Solar and deep cells for the lighter loads. AC just pull the juice.. It's like two "broiler toasters" or something and that kick on serge.. It's power killer!

yeah, thats a lot of wattage to get via solar, I have one of the most energy efficient AC units available, (and I checked everywhere) a Frigidaire 5000 BTU unit that has a 9.7 energy efficient rating and it pulls 515 watts and 5.7 amps.
The EXACT amount of Wattage is 515 watts. This is because of the unit's 9.7 "EER" (Energy Efficiency Rating). If you take the BTUs and divide them by 9.7, you get 515. 5000 / 9.7 = 515
my small solar kit I have consist of 3 solar panels that are 3 feet x 1 foot each and is only a 45 watt system. for a total collector size of 3x3 feet, and I would need 12 of these systems to make enough wattage to run the AC unit or a solar panel that was 3 feet tall by 36 feet long. or if you stacked them in 2 rows on the roof it would be 6 feet x 18 feet, granted my unit is an el'cheapo harbor freight unit, I am sure more efficient panels are available but cost a premium. you would need a very large battery bank to be able to keep up with your wattage usage.
You need from 57 to 68 amps DC through an inverter to make 5.7 amps AC (10-12:1). That means a standard Group 24 AGM battery would be killed in an hour. 1 battery per hour of AC use @ $170 and 50lbs each... Ouch. To keep up via solar, you'd need about 800 watts of solar panels... I'm so glad I live north of the AC belt.
