We just moved into our LM365 Newport on Thursday. The hot water heater had been turned on for 24 hours before my wife took her first shower. She had less than 10 minutes of hot water before it turned ice cold. Her second shower tonight was the same way (I shower in our bathroom in the garage). We even have the oxygenics shower head to reduce water usage. I know something isn't right. We are only running off of electric on the WH since we are inside the garage and don't want the fumes from the gas. We had more hot water than this in our old Landmark with a 10 gal tank on elec only. We can't take it back to our dealer to get it looked at since we are full timing or I would. I checked the bypass and outdoor shower. They are as they should be. Am I missing something? Any help would be appreciated.
