Hot water heater upgrade

I have a 32QBBS 5er. Has anyone upgraded there hot water heater to a larger one. Also does the electric and gas heater produce more hot water faster when you use both. How hard is it to upgrade and does the larger one give you alot more water for showers.

Yes, you can use the gas and electric together to nearly cut in half the recovery time. As for installing a bigger unit, I will seriously consider it when or if the time ever comes for a new one. Maybe an even better upgrade would be to a demand heater. Bosch and at least one other company (forget who) make them for RV's and they fit in the stock location.
