I used to have a Tvan for 10 years and know how hot they get inside the rear.
Having a fridge in there as the Tvan mob suggest, is ok in cool weather but not in hot weather. The fridge, especially when running as a freezer, simply stews in it's own hot air and the Tvan inside temp does not allow for the condenser to be cooled by the Waeco fan which is minimal in airflow anyway.
I have a slightly smaller Waeco and decided never to use it in the Tvan. It sits behind the drivers
seat and is heavily insulated with additional insulation panels other than the, pretty useless, proprietary bag they supply.
I often have an old sleeping bag over it and also use a reflective poly sheet over it. It runs at more than -10C in daytime central OZ and will get down to -18c if needed to. Most times there is no need to cryovac if the freezer actually works.
The fridge/freezer has an additonal fan 80 ma draw of current which turns on when the internal fan runs and that external fan supplies cooler ambient air to the internal fan so the fridge can work properly.
Overall amp consumption is reduced too. Your fridge must be working full time and using plenty of power each day and that will not change with cryovac food at the temps the fridge is working in.
