New water heater?

[pigsfly]

I want to upgrade the hot water heater in my 61 Overlander International.
Is there a standard replacement for the old ones that will fit into the old space?

Take out your old one and measure the opening then google the website for Atwood Hot water heaters or Surburban Water heaters and each site will give you the size opening you need for the model you pick.In some cases you may need to add an aluminum filler to close the hole up if the heater is smaller that the opening.
Have fun while you are doing this,don't let it be work---
