water heater on rv not working, would like to use small residential one instead

I have a '93 Fleetwood, not driving for now. Couldn't get propane for a while, When I did, I discovered the water heater is just trashed, corroded, useless. A friend gave me a 10 gal electric residential water heater. I will install the electricity directly to the main house breaker box with it's own 20A breaker. What I need is instruction on unhooking the water lines from the rv water heater and routing them to the little electric one. Do I really need to completely remove the old rv water heater? Or can I just unhook it and leave it there until I'm ready to buy and install a new one?

It's your RV so you can do what you want but you'll need to do some additional plumbing. For temporary use you might want to consider https://www.plumbingsupply.com/flexes.html

I've done quite a bit of plumbing. My old house had 2 old water heaters that I replaced myself. Then I bought some tankless water heaters, one NG and one elec, which I also installed myself. I was just wondering if I should remove the old one to get to the water lines. I've done some more reading about it all, and it sounds like it would make it much easier to get to them.

I the long run, it is almost always easier to remove the old and give yourself some room to work. Old water heaters had a different type connection than the newer ones with heat traps at the connections so you may have to make some changes anyway. But in both cases, the hardware is pretty common so you can find or make caps for the lines pretty easily.

We added an on demand HWH to our RV. An ecco temp 5 serves us very well.

You can bypass the HWH on the coach. Just be sure to cut off the correct valves going to, bypassing, and coming out of the RV before connecting the new tank. If the new tank is pressured from the house and not the RV, the connection is easy, just run a connector hose from the outlet of the HWH to where the RV HWH was attached. Be aware RV connections are usually 1/2 inch and residential HWH's are 3/4" inch.
