I am not sure what heater you have but on my Suburban there is no problem using both at the same time. Speeds up recovery and saves on propane. Just be sure there is plenty of water in the tank when you turn on the switch (and be sure to turn it off when you are done for the trip). The electric elements only require seconds to burn out.
I thought gas was faster in regards to recovery time.
I would not use both at the same time.

Gas is faster than electric but both are faster than just one. Plus it saves you on propane. There is no reason I know of not to use both. If you forget and burn out your electric element, the gas will still work and it is an easy and fairly cheap fix
Using both is fine. And as many have mentioned just make sure you always have water in it when on. Also keep in mind its on if you need to conserve power when running a generator or other high amp draw items on limited power.

Funny story about me and my water heater. I couldn't get it to heat up using electric early this camping season, so I just used gas for the first few trips. Then I got serious about getting it fixed. Thought I needed a new element, so I bought one and installed it. Still no hot water. So I got out my tester and found that I had no power to the element. Long story short. I had unpluged it while winterizing as a precaution against turning it on before filling it with water( it worked). Totally forgot about that plug in the closet. I think I'll unplug it again this year.
