There are absorption refrigerators which operate like traditional RV refrigerators (run by heat), but work only on electricity - not propane. These are extremely rare, although sometimes used in hotel rooms and dorm rooms because they are quiet. Because they don't burn fuel they can (and do) exhaust heat within the room. That would address the outside vent issue, but there are so many other problems with this design that I certainly wouldn't want it.

If I had a trailer prepared for a compressor-type refrigerator, there is no chance that I would vent it to the outside. The heat being pumped out a refrigerator is mostly heat that came into it from the trailer interior anyway, so very little would actually be added to the interior. An outside-vented refrigerator is a very small air conditioner - because it does pump heat out - but that slight benefit would not be worth having the vents to me. If it is so hot outside that the refrigerator heat is an issue, an outside-vented refrigerator is going to struggle anyway, since it is pumping heat up such a big thermal gradient.

If you're not using propane to provide that heat, you're using 12v or 120v heating elements, and those each heat the liquid or gas that heats and cools and runs the fridge. Air has to come in at the low vent and exit through the high vent, even without propane. Since you've been on the forum for several years, you may have noticed one owner who switched to a compressor type fridge at great effort and modifications, with 4 or more batteries. ETI has not chosen to go that way, but you can always ask. With the changes in the air, you never know.
Venting isn't a problem, per se. There are several compressor based fridges that will work in an RV - and some are self venting.

But, go ahead and ask if you feel strongly about it. The answer will be a no. Trust me, several have asked before.
