???

I have a catamaran cruiser 35 Getaway model. Its time to change my hot water heater (6 gal suburban lp). I was wondering is any one has the 6 gal LP/Ele model and would that be a better choice than the Lp model I have now. I winterized my boat and didn't know all the damage anti-freeze does to the tank. I will put on shut-offs when I replumb. Is the extra money worth having the combination LP/Ele.

I am a first time member and this is my first question.
