I’ve reviewed a few different compressor refrigerators. They work great! I had one in my RT for years. They sip energy. I’ve finally settled on a Novakool RM 4500. I’ll never look back. Larger than the original and stays the exact same temp you set out at no matter the heat outside. I love it. I do have 200w of solar and 200amps of lithium batteries.
The. Portable compressor fridges are much cheaper and work very well also.
Here is a review I did on a Chinese model. I’ve also reviewed Iceco models too. Hope this helps.
