That's good to know. Coleman Power Saver series have promising specs except for the height being listed at 13.8-inch high -- although only 26.1-inch wide. Because of narrow width it may not add much drag compared to some low-profile units (not that it makes that much difference), but it may add a few more inches to motorhome height depending on what else is on roof. Added room for larger coils apparently helps make these more efficient.
