Tewitt, your Vietnam fridge was likely made in Japan or at French factory in 'Nam. No comparison to cheap Chinese items of today.
The problem with cheap fridges - assuming you are talking 110V fridges rather than propane - is not only a short lifespan but low efficiency, they draw more energy to do the same cooling job. It doesn't sound like you have any solar or huge Li battery. This means that you will run generator for long hours every day just for the fridge, when offgrid. Cheap compressor fridges can also be annoyingly loud, except for small 110V absorption type fridges, but those are probably less efficient than cheap compressor fridge.
Average 2-way propane/110V fridge in TT can last +10 years.
