etrailer had the best price and shipped this thing fast. I also got the water heater door kit since my rv is older and had a larger cut out. The electric by itself gets very hot combined with the gas this unit will give you long showers. I gave 4 stars because the box was now sealed properly luckily nothing fell out
Initially I was worried about whether all my existing wires would correctly line up with the wires on the new unit since my old unit was discontinued. It was perfect. The water intake and outflow on the new unit was aligned differently so I had to get a couple of fittings and crimping tool... Was in the end a jiff to install and worked perfectly. Just remember to always winterize from now on lol. I highly recommend the products I purchased.
Package arrived very quickly in perfect condition, less than one week, sooner than expected.
I am building a cargo trailer conversion and won't install it for a while. I wanted to have for placement location planning. I am confident it will perform as expected.
AND ! the customer service is excellent ! I was even emailed directly by my sales rep with shipping updates.
It does not seem to get very hot. Is there a temperature setting I missed? Otherwise went in easily.
Replaced previous Suburban water heater which was no longer turning on and showing lots of rust. Close to drop in replace but note that the Suburban has rounded corners on the frame and this unit has square corners. Had to use a nibbler to square out the opening on my RV siding. Fortunately the wood framing was a perfect fit as well as the gas connection. The water connections are different. Suburban had a top/bottom hot/cold connections and this is left/right, so had to redo the PEX connections. Be sure to buy the control switch panel and note that the control wires are not that long and had to extend them. Only stars as I'm experiencing the P/T valve dripping after heating up. The manual says this is normal but it is dripping on top of the other components.
The help I received from the first phone call to receiving the product in mere days was AWESOME!! I have not installed the new hot water heater but will give you all more feedback. Thank you all for your assistance!

Sucks!! I have to change the control board last month $xxx dollars later
Exceptional service, package arrived on time in great condition.
It was easy to install. The water is very hot! And recovers quickly. I highly recommend it!
I gave a 3 since both items were to be rated together. The water heater would have received a 4 and the door kit a 2. Reason is the door corner was bent and paint cracked on a corner. Chose not to send back and wait since the water heater was installed, needed to get the front covered. Package did not look dented, but guess it could have been dropped by the shipper.

Product works great
Easy installation, works great.
We have Hot Water ! We live in our RV full time so we needed a Hot Water Heater of good quality. Time will tell if this Dometic Hot Water Heater is as good as the old Atwood which it replaced. The packaging was good ! Hot Water Heater appears to be well made. No problems installing the directions were clear and it fired right up. This replacement Hot Water Heater is smaller than our original so we purchased the enlarged door kit which fit perfectly. Great communication with etrailer which helped us find the correct Water Heater for our application. There website information was accurate and we had no problem contacting a human voice when needed.. We are Happy Campers !

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..
Part delivered as promised
Easy installation! Works great!
Installation was easy, I did have to raise cabinet drawer up about 1 inch to allow clearance at the back for the water connections. It is quieter than my older (2000) Dometic and hot water recovery is a little faster.
Needed a water heater and this was the best one to fit, after reading the directions front to back it took only a couple hours total to get it in my RV. Water heated up immediately and everything has run great, of course it's only been a few days but so far so good, my only issue is that there is a back order on the door cover.. so it's totally exposed to any elements and I have put temporarily back on the door that came with the RV ( even though it doesn't fit) it's just so it's not totally a open hole to the outside, hoping it is available sooner than later.
My water heater leaked and It was the old style that is no longer available. This one needed some conversion but it fit. I even made a pan to go under it in case it leaked again.
I used two 1/2” supply lines to make the connections because they were in different locations. Worked like a champ!
Had to use the door conversion which fit perfect.
Thanks great item every thing worked out
Water heater showed up on time, it was the the right application due to Atwood being bought out by Dometic, fit perfect with conversion door.
It's been one year since we replaced the water heater in my 2006 Jayco Feather and there are no complaints. The new water heater is working great and etrailer was a huge help when I purchased it. If you're replacing a water heater, I would read the Question and Answer section on here for the model you are going to buy. And also pay close attention and figure out if your current water heater door will work with the new water heater. They may vent in different places.

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.
The purchasing and shipping process for etrailer was amazing. I made this purchase over a weekend to have it arrive on a Wednesday as the website indicated. There was a problem processing a payment and I was contacted several times by Andy to ensure the problem was rectified and the heater was shipped in a timely fashion. My water heater arrived a day earlier than they estimated on top of the processing issues and once it was delivered, I received an email confirmation which also included a link to documents related to the installation process
I only had two minor issues with the heater, but they do not negatively affect etrailer.com. It arrived with mounting options for the front door on the top corners instead of with the center tab as indicated in the pictures and also how my previous heater was setup. I thought it was going to be an issue as I didn’t purchase a new door, but I just moved one mount to the center position.
Second, this water heater did not come with any mounting screws. I’m sure that’s Dometic’s choice and I was able to reuse my old hardware. So just a heads up for anyone in the future.
Overall, thank you etrailer.com, everything worked out great!
The install process was easy and it’s working better than my old heater ever did.

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 ;)
Water heater was delivered yesterday. I just installed it for a customer this morning. Everything went smoothly. Tested the water heater before finishing sealing up the outside flange with butyl and screws. Heater was working great on both propane and electric. No leaks the customer was very happy to have it working again.
Exactly what I ordered and it was plug and play. Delivered in 3 days which was a plus. Thank you
Propane works great! The electric side not as hot water easy install, yeah right. Takes knowledge to install, which I have , the rerouted propane line was a challenge, under carriage to redo line and flare fittings , also a better description of wiring of gas and electric low voltage, I went with colors to match but didn’t want to damage unit
As always with ETrailer, we received great assistance and accurate information. The water heater took a couple of hours to install as a couple of adjustments needed to be made to get it into the space. We are up and running again thanks to ETrailer and Andy!

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.
