I have a arb cooler, which uses the danfoss compressor. this thing pulls 4.5 amps when running. in a car with a h7 battery it will be unable to start in about 2.5 days.

Group H7 isn't a particularly large battery size - only around 40-60 amp-hours.

Just one Group 31 deep-cycle battery will provide around twice as many amp-hours - and will increase your fridge's run-time accordingly.

Sorry about now responding in such a long time. Both friends decided to get generators in the last second. After all they decided that air conditioning would also be needed.
