It measures about 11/16" in diameter and 4 7/8" long. Thanks Brian
First propane works faster, cheaper and better than electricity. You just think electric is better when you aren't paying for it directly. One option is to simply say "I have a propane water heater" and forget about the electric element. I fulltime, rarely turn my water heater off, and don't go through a 30 lb. tank in six months! An electric heater will take 15 minutes to recover - on propane, 5.
Next: old water heaters - are they worth repairing? IMHO, NO. RV water heaters - simply because most are 6 to 10 gallons, get a heavy workout while camping. They will rust and get pinhole leaks - worse if that happens on the propane tubing than in the water chamber! After a while you're betting your life on two chances - will it catch your RV on fire, or will it kill you with carbon monoxide poisoning? If the water heater in the Argosy is original it's over 20 years old, probably over 30. Even if it's rarely been used, the elements have gotten to it unless it's been in climate controlled storage the whole time.
The cost of a new water heater? Compared to the cost of a melted RV?
Now if the water heater IS newer, just look for something generic at Camping world. Take your current element with you when you go looking.
