Reflection 312BHTS travel trailer vented or unvented dryer?

I do not see where that trailer comes standard with a Washer/Dryer. Did the dealer install it? Generally speaking, vented dries quicker. I checked the GD website and I see no mention of a W/D installed or back up camera wiring being installed on the Reflection Travel Trailer line up.

You can ask over on the granddesign owners forum if you do not get many responses here. Lots of Reflection owners over there.
