or
Negative Ground, Max 150V(Voc) PV input. A higher input capacity will allow you wiring more solar panels in series to minimum pv currentAdvanced maximum power point tracking technology to optimize the solar system. This 40A MPPT solar charger 's tracking efficiency can reach 99.5%Support 4 charging options: Sealed, Gel, Flooded and User-defined. Compatible with AGM batteries, User mode allow you set your own charging parametersOver temperature, over charging, PV and load short, PV (battery) revered, over current protection. Comes with RS-485 communication bus interface, It is Standard MODBUS interfaceThis 40A Charge Controller works with Max 600W Solar Panel Charging a 12v Battery System, or 1200W Panel on 24v Battery System.

Can you tell me how big the camper is?
We need to know the surface area to start with, because you said 'small teardrop shape' and '600 Watts'.
That's a tall order. Also, what's your budget?
EDIT: I read your post wrong. You're saying your loads are 600 Watts for 6 hours. That's 3600 Watt-hours, or 3.6 KWhrs.
Even if you had 100% efficiency in the system (impossible) you'd need 900 Watts of solar panels to possibly get that much power in a day.
You'll likely need to invest in Lithium batteries, as probably nothing else is going to be dense enough to give you that kind of usable storage in a small space.
You'd need:
900 Watts of Solar Panels
A 24 volt battery bank (because you'll be charging at some hefty currents otherwise, and Lithium is harder to get in 12-volt ish than 24-volt ish) with AT LEAST 190 Amp-hours of capacity. (4.56 KWhrs!)
Consider Tesla packs or other electric car packs that you can re-wire for your purposes. Or, be prepared to shell out at least $5k for the batteries.
A 40 amp MPPT charge controller.
Consider this one:

And finally you'll need a capable inverter that will be able to work well with Lithium batteries and be able to use a shore power connection to charge them back up if there's no solar coming in.
The only inverter I know of that allows enough customization on the charger half to work with Lithium batteries is the Magnum Pure Sine Wave inverters, they come in a 2000 watt model iirc and their voltages can be set to cooperate with lithium on the charging half, I think. (Do double check this. I don't personally own one at the moment.)
This should help if you are referring to my setup link.

How did you come to the conclusion that my laptop will draw 2 amps at 120v? Did you get the number from this part of the power supply?Nevermind, I figured out how you came to the conclusion using the max wattage and amperage to come to 120w.
