Congrats and welcome to the forum.
If you live in a place where there are HARD winters with freezes, make sure you empty the water heater completely using the main drain that is on the outside of the water heater. Open the access door and use a socket wrench to remove it. I busted a tank once because I forgot to do this and it froze.
If you are using the fresh water tank and pump, Always turn your electric water pump OFF when you are not actually IN the trailer.... that way if you have a leak, it will not go full bore.
We recently had a BIG leak. A pipe joint just came loose. I noticed it while filling up the hot water tank....fortunately the leak was under the sink and easy to fix. Just be alert. I noticed this because the pump just kept running and running. Fortunately open pots and pans, and towels caught most of the water. If I had left the pump running and just walked away to do something else, it would have been a disaster.
The floors are made of plywood not particle board so one leak does not destroy the floor.
On our 08, the water heater is gas operated but ignites electrically. If yours is the same: make sure it is full of water by running the hot water at the sink. Make sure the gas is flowing my testing it at the stove burner. Then just flip the hot water heater switch located somewhere in the kitchen and wait. You should hear it ignite...but its not very loud.
We never hook up to a water hose....we always use the fresh water tank and pump and just fill up when need. We do this even if water is available. No particular reason. On a previous trailer, we hooked up to city water that happens to be 60 PSI and did not use a pressure reducer.... it totally blew the plumbing and flooded the trailer with 2 inches of water before be noticed....ruined the particle board flooring. (old trailer...a Prowler). ALWAYS use a pressure reducer if you are hooking up to a water supply...otherwise just fill the tank and use the pump... no big risk in that.
Well, there is the risk of having a dirty tank with mold etc. We clean our out once a year with 1 cup of bleach and a full tank.... then flush it real good.
