Another item of concern for me would be the very large choice for the POWER INVERTER. A 2000 watt unit will want to draw around 160-170 DC AMPS CURRENT (or more) if fully loaded down and this will do a big number on your truck start battery system.
The 120 vac electric heating element in a 6 cu ft gas absorption fridge is ~ 300 watts which in turn means a 25 amp draw @ 12 vdc not including inverter loss ... worst case I'd expect the truck's electrical system would have to supply an additional ~ 30 amps max beyond it's normal load in order to run this fridge so there's no need to use a 2K inverter when a 1K would suffice nicely for this task. That said, I still don't see why the OP wouldn't just run the fridge on gas as it was designed to do. :h
