An air conditioning system provides cold air on demand at any time, and is unlimited for as long as you have power or gas.
The thermal storage can be "recharged" with an onboard heat pump. Most likely one based on a 5000BTU/hr window A/C since it's hard to go smaller with decent efficiency and still keep the cost of parts low, while going bigger increases weight and size. (And are you planning to have more than 500W or so of solar panels to be able to power a larger A/C constantly? Might be reasonable for a RV but not a van.)

4kWh of batteries would be overkill unless it's also being used for traction power. Could probably go that route fairly easily by replacing the alternator with a BLDC motor/generator.

To my surprise, shortly after Naomi Wu gave me a bit of fame for making good use of solar power, Allie Moore got really jealous of her...
