Water heater question

I have a 2002 36' fleetwood expedition, the hot water heater tank split open. It was a Atwood 10gallon. Am going to up grade to a Lp/elec, but
thinking of going to a 6 gallon instead of the 10. Water would heat up faster, & use less energy, but would it be enough hot water. Not sure what the newer m/h have in them.

Don't do tankless only work on propane and are $$$$. Also I think the hole in your motorhome is to big for a six gal hot water heater

I had a motorhome with a 6 gallon water heater. The motorhome that I have now has a 10 gallon water heater. I vote for replacing with a 10 gallon water heater if possible.

I agree! I've had 6 gal water heaters in the past, took real short showers or ended up cold, have a 10 now. Well worth the extra few $$.

It's funny the things we miss in life, I grew up in a house with instant continuous hot water, then when I came to Canada I have always had hot water tanks and hated them now at 63 I can't wait to put a tankless in our motor home.

Thanks for the link B.Cooke that's an expensive one but it has great output too!

Dumped the 10 gal water heater for an Atwood tankless before driving off the lot. Did a 1 week shake down trip and I loved the long hot shower after doing laundry!

I haven't researched RV tankless water heaters but I have been researching whole house tankless water heaters. They all claim to use less gas than the tank versions. First they claim higher efficiencies (as does the RV version in the link above), second you are never heating and reheating stored water.

But if you never run out of hot water you may take longer showers and thereby use more gas.

Would like to thank everyone for the feed back. I thing I am going with an Atwood 10 gal LP/Elec/dsi. Will fit & plug right into my existing wire set up. Working with PPL out of Texas, very good to talk to & best price so far. Really don't want to put in a lot of expense, because I have it for sale.

you can have your split tank welded. mine split the local shop welded it up for 60.00 buck. I never thought it would be possible ! The split was HUGE !!! But the guy did a great job. I've been using it for 2 years now no problem . If I could afford a tankless that's the way I'd go. I bet you'll do a better job of winterizing next !! I know I learned a lesson ! HAPPY TRAILS TO YOU !!
