There a number of problems with absorbtion fridges. The first is that unlike compressor fridges, their cooling efficiency is dependant upon the outside ambient temperature; in other words, if it's very hot outside the fridge may not cool the inside suffiently. I think they will only cool to something like 30C below outside temperature. The second (and related) problem is that if you're going somewhere hot you will almost certainly have to add an electric cooling fan to provide the necessary airflow to achieve effective cooling. This can require you to uprate your leisure battery set up. The third problem, though modern fridges are better at this, is that absorbtion fridges are very sensitive to pitch; in other words if you're at an angle (as little as a few degrees) they won't light or stay lit. The fourth problem is that these fridges are very sensitive to even minor damage/displacement of the gas safety features, in other words they can require quite a lot of maintenance.
To be honest, in this day and age compressor fridges are the way to go. You needn't have to go down the Waeco or Engel (expensive) route. I fitted an Indel 12/24V fridge which was far cheaper and does the job perfectly well.
