Reflection 312BHTS travel trailer vented or unvented dryer?

In the Reflection line, the plumbing and AC prep is there - the outside vent hole has to be cut, but is marked. You DO NOT want a non-vented dryer unit dumping all that moisture into the rig. That said, RV washer-dryer units, especially the combos, are only capable of very small loads.

The brand-specific forums (in this case, the Grand Design Owners' Forum) is often a very good place to ask this type of question. Great bunch of folks over there.
