After seeing you video Ray on the Ivation, we got the model 1 size down for our 28 ft 5th wheel. This thing has been a game changer! Love it. It is a 14 point and we are running it pretty much all day. Have emptied it twice a day. It is keeping humidity at between 40 and 45. Not a drop of condensation anywhere. We sure notice how much warmer and more comfortable it is in here. We also run a small electric heater during the day and have furnace set at 62 degrees over night. Thanks for the recommendation of this product. Suoer pleased with it. Also hoping it is just for this 1 winter!
