Larry can you show me where it states that within liquid tite out doors it is considered a damp / moist/ wet area???The NEC does show us that if in pipe and underground the conductors must be rated for a wet location,but I have tried to find where it states that if within flexible non metalic conduit that is not installed underground the conductors must be wet location rated.
100 - Watertight.Constructed so that moisture will not enter the enclosure under specified test conditions
100 - Weatherproof.Constructed or PROTECTED so that exposure to the weather will not interfere with succesful operation
356.10 (2)Where protection of the contained conductors is required from vapors,liquids,or solids

IMO that about covers it. You will have condensation in an outdoor installation.
