I obsess over details and start overreaching/overspeccing but find that it helps to step back and make decisions on real-life expectations. Definitely wanted a dual zone chest for off-van versatility and...popsicles. The biggest impact was floorplan and cabinet layout.
With that, I ordered a dual-zone 50L cheapo model for $369, plus a 3 yr Amazon/Asurion warranty for $34. With 250# rated, 18" lockable drawer slides, I plan to call it good.
Sounds similar to what I did. Counter space above, tucked away until needed.
