I tried the Revolution 1141-250NL. They were pretty bright and because of the shape of the bulb, it would illuminate one side more than the other. Not a big deal unless you are very OCD about your camper
For interior lighting, I will keep my recommendation of keeping the FWC incandescent light housing and just replace the bulbs with sensibulbs. Yes, expensive, but less than the FWC LED package! And you end up with better, warmer, lights.

I'm not sure which Revolution bulb you used in your test, they make several different bulbs, to compare apples to apples. I went with the 300 lumen Revolution and do not think it is overkill for the outside. It's slightly brighter then the oem FWC incandescents. But uses 1/10th the power, that's good isn't it?
As far as the interior lighting I went with the Kaper II Led lights, this is what FWC is using for their Led lighting upgrade package. Easy install but not as bright as the original incandescents that I removed. For the same price I should have just replaced all 4 of the incandescents with the 300 lumen Revolution bulbs. This would have at least been as bright or brighter then these crappy Kaper II's and just fit into the existing light fixture.
IMO these suck:
