I have a Valor 36v11. Not sure if this will work in other models, but in the closet in the bottom corner there is a removable panel. If you remove that, you can snake some flexi-duct down and over to the bottom middle of the cap. There is a pretty good size opening under RV pin box. The distance is quite short. I plan on venting out that way. I will probably wrap the flexi-duct in some parts in foil tape to make pulling to the opening a bit easier I might have to rig a special vent opening under the pin box, but it is a perfect location. Also debating whether to take up the floor to add nonexistent insulation 😞. It would make the dryer ducking a lot easier and a bit more professional.
