That is so great to hear, Robert - glad Andy was able to help you out on this order and keep you in the loop! It's good to know what actually comes with it. Having the heads up is nice for other folks to have! Glad you have hotter water than ever ;)

This water heater started leaking underneath the tank shortly after I posted this review. I was out of state and couldnt do anything about the leak until I returned home. I called Dometic to see if they had any advice for repairing the leak. The person I talked to said the tank may have had a bad weld on the seam, it was out of warranty, no advice, and basically not their problem. I wont buy this brand again. The original Atwood water heater lasted for 20 years. Its not the fault of eTrailer, they were great.

One Year Later ~ Hot water Heater is working very well. Pros~ This replacement water heater seems to recover faster than the original. My previous hot water heater was only propane gas so this one has the electric option which works well. Cons~ Burner flame blows out when we have a 20 plus MPH. east wind directly. There are no flame adjustments just a circuit board which controls all the settings.. This hot water heater needs a external wind screen protector to mount over the door to keep the burner flame from blowing out..

The first thing I'd check out is the water heater bypass valves! If the valve is partially open or aren't in normal-use position cold water can mix with hot water and make it seem cooler. A good test is to let it heat completely and check the water temperature right at the water heater's hot outlet. If it's hot there but lukewarm out of the faucet, the problem is almost certainly that the cold water is mixing somewhere in the RV. The DMC74FR doesn't have an adjustable temperature control and is preset around 130 degrees, so if the water never gets close to that temp after a complete heating cycle, I'd look at the heating system. Like if you're running on propane, make sure the burner has a strong, clean flame and the burner/flue isn't obstructed.
