From what I have seen few absorption fridges in RVs are in a cabinet shaped for good operation. The hot air from both coils and flame/heating unit must not pool at top of chamber. And all air must be guided past the coils to pick up as much heat as possible.
While what you mention is true, OP is talking a 2004 RV, I suspect that if incorrect cabinet design is at the heart of the issue, someone would have corrected that by now and I highly doubt that the previous owners would have put up with a completely non functional fridge so many yrs (17 yrs is a long time to put up with a non functional fridge).
17 yr old fridge not cooling on gas or electric, most likely operated out of level more than once, yeah, cooling unit is most likely shot by now.
Shame the previous owners did not disclose the broken RV fridge.
