Do you have enough fresh water tank capacity to devote so much to hot only. Once you reach 20 gallons you will have zero hot water available.

Fill fresh water tank.
Fill water heater.
Fill fresh water tank again. You will now always have the full capacity of the fresh water tank available.

Of course, OP says he is on shore water.

thanks all, heater is 120 volt--water is directly pumped into trailer & branchs off to faucetswill use pex love that stuff.

Most 20 gallon tanks are 220v, do you have that available? If not I picked up a 110v 12 gallon one at Lowes, very happy with it so far.

As others have said, anything is possible. I know of several places that locate their water heater in some outside location.

pex doesn't like sunlight. otherwise no problem. alot of homes in the southwest have their hot water heaters outside.

I think it would be very feasible, it's just a matter of running the pipes and wire into the trailer.
If you use Pex Tubing and SharkBite Fittings it should be farily simple.
Just make sure the Pex is protected from the sun if it's exposed, pipe insulation should be sufficient.

If old heater is gong to be removed then you can use 1/2" PEX plumbing to connect that new heater to the cold and hot water plumbing lines for old heater. Pipe insulation on the hot water line..
Then you will need to run AC power........course that will need an AC circuit breaker and a AC ON/OFF switch. An it would need to be a 120V AC water heater....they use a 2000W element so initial heating of that 20 gallons will be slow but should maintain/recover OK.
Run them and the electrical right out compartment access....insulate that opening/space where old heater was.

It would require some creative plumbing, but anything is feasible with enough time and money.
