I agree in general bigger is better towing, but the 2.3L EB I had in my Ranger was a really great engine - pulled our 20' Airstream (~5000ish) zero issues. That LC 2.4L may not be able to make 200 hp and 2200, it will just settle where it needs to RPM wise to make the required HP and don't see that being an issue, personally.
To me it's more about engine stress long term - if towing often bigger engines generally make more sense since they are less stressed and easier to deal with, short term, niche use cases wouldn't necessarily sway me one direction or another.
May be a dumb question - does the hybrid supply power at any speed / RPM? I honestly don't or didn't know the elec motors were being utilized at higher speeds and/or if they are HP demand based vs speed based.
