New Camry longevity (15yrs), gas or hybrid?

This may be somewhat involved, my apologies.

I've owned a Corolla, Camry, and Lexus ES350 as daily drivers before.

We own a Ford F250 for pulling our camper. I DD it now but really don't need it's size, crappy ride, an 14mpg just to get to work. Wife has a 3 row SUV for general family duties.

I have an 8 year old daughter and 5 year old son. I'm considering buying a 1-2 year old Camry which would be my DD, let the truck stay parked, and in 8 years could be my daughter's first car, and maybe 3 years after that be my son's first car as well.

For an ownership plan of 10-15 years, which engine would you choose and why? I definitely preferred driving my 3.5 ES350, but I can make do with any of them. Hybrid seems enticing for the awesome economy, but I also enjoy the simplicity of a basic Toyota. Am I overcomplicating my future maintenance with a hybrid?
