As for the quality issue, it's underexposed and appears to have a greenish tint if my eyes are working correctly this morning. The IP refusal is the result of not having property releases for the trailers. You would need them, just as you would need one for an actual home.

It may depend on the moderator's understanding of when a property release is required. From my point of view, an RV is a home, or at least a home away from home, and could conceivably require a release. I'd make the quality corrections, look for any logos on the RVs, and try again. That's one option.
