Agree! I will have 420W with 280aH of LifeP04 in the 6*12 build, so no worries on that... that's why I don't mind going cheap on the fridge. They seem to work well and are reliable when powered with a pure sinewave inverter. Also,I prefer the vertical fridge so I can see what I have without digging. When loaded, not a big deal if some cold air drops out.. thermal mass is what is most important.. 2.5 CU is equivalent to 70L so it is large in those terms.
I have a 4.3Cu Ft (122L) in my 7*18 that I have been using for 4 years and it has been great! Lived in the trailer full time for 3 months last year and it was nice having the larger fridge. I have 800W solar and 225aH usable (FLA batteries) on the 7*18 and the fridge was never really a concern unless I had no sun for a few days.. I tend to use a lot of power on lights, fans, PC, radios, amd etc..
