Not sure the OP has a carbed engine. I only read convertible. I store a lot of stuff, including John Deere zero turn mowers and generators, for several months at a time, all of them use E10 and get stored with full tanks to limit condensation in tanks. They even get filled with bulk stored gasoline. I do change out the filter, along with oil changes, in the spring. I do use a stabilizer product, for sure, but I have no issues with any ethanol laced fuel. And those mowers and generators have carbed engines. A injected engine would be even less of an issue with E10.
Modern vehicles have ventless fuel systems, so any water associated issues with ethanol would be virtually non existent. Especially if they top off the tank before storage along with using a fuel stabilzer product.
