I have a 2018 Thor Gemini 24TX. I'm convinced that the designers of this coach have never owned an RV. The location of things just baffles the heck out of me. For instance, the direct furnace, non ducted, is located directly across from the bathroom door, nearest to the floor. No provision for directional control other than straight out. Would it be okay to replace the front grill with a 4 way directional grille?
