I have a Dometic CF-35 that draws 4 Amps when running (48W) but it only runs 1/4 or less of the time, so that would come close to your requirement.

But, it's pretty large.
The CF-18 is somewhat smaller outside: https://www.amazon.com/Dometic-CF-018-D65-B-Portable-Refrigerator-Personal/dp/B0136TQ65Y/
The CF-10 is smaller, still: https://www.amazon.com/Dometic-CF-018-D65-B-Portable-Refrigerator-Personal/dp/B005X97OHA/
That won't work, unfortunately.
A solar panels' 'nameplate' power is only produced in cool weather and the panel pointed to the (overhead) sun.
Enter San Diego into http://pvwatts.nrel.gov/, change "DC System Size (kW):" to "0.1" (100W), and change "Tilt (deg):" to "0" (horizontal), on the last page you'll see the monthly" production under "AC Energy (kWh)", divide by 31 to get the daily numbers (the juli/aug 16kWh is 500Wh/day), and your 60W cooler needs 60W x 24hr = 1440Wh/day (thermoelectric coolers are very inefficient).
More expensive are compressor coolers, 3A average according to "customer comments", and (they say) it will 'freeze' stuff in 1 hour, if your "need to keep something cool" can handle ambient temperatures like can/bottle beverages you can install a timer to run it only at let's say 11:00-13:00 for lunch and 16:00-22:00 for dinner.
>so I have decided to use whatever I will have for solar system as my starting battery
Bad choice, a 'starter' battery is designed to give a very high 500A? 'starting' current (thin plates for a very large surface area), a 'deep cycle' has fewer but much thicker plates for a current of ~1/10th the capacity (12A from a 120Ah battery).
There are ways to charge the 'domestic' battery from the car alternator, example (pdf) uses diodes, to find out if a particular setup will damage the deep-cycle I suggest you google-fu RV/boat-users websites (the -shops* only want to sell things).
If you like electronics, or know someone (highschool tech dept.?), a small CC-CV buck-boost converter's input can be connected directly (via a fuse) to the (12V) panel, the output, via a diode, to the starter battery, the "CC" (constant current) will limit that to whatever you set it (0,5A?) and the "CV" can be set to 13.8V? (max starter battery voltage), that will keep it 'topped up' from the solar panel without draining the domestic battery.
You do need a 'battery charge controller', an MPPT is recommended.
Edit: word
How about 330$? Ive had this for 3 years now, works a champ. I keep it as a fridge but for a few months i cranked up to freezer temps and could even keep ice cream solid.
