The smallest unit is $3,000 and puts out 3.3 A; 40 watts. The only conditions under which this would make more sense than a small solar system is in the far north where there are months of no sun.

Yeah, but ... for their smallest unit (Comfort 80) that can happen continuously for 24 hours every day if needed ... that's 80% of a 100AH battery restored to full charge every day under ANY conditions (unlike solar).
Does your RV consume more than 80% of a 100 AH battery every day? If it does, get the next size up EFOY unit.
The EFOY units are for absolute power independence from outside conditions for replenishment of RV battery bank power... their purpose is not to compete with solar - price-wise - for the few hours a day/week that the sun may be shining.
IMHO, they're great technology that's about the finest out there for 24/7/365 RV battery energy replenishment at this time. But as usual, you have to figure out how to pay for this kind of service if it is of value to you.
