#3. Crew cab 3/4 ton anything back 10 years, gasser. Ford V10 or GM 8.1L if you have any thoughts on getting a larger RV. You'll love having a pickup.
Regarding "Storage in truck difficult for groceries, stroller, kids day to day backpacks, dance bags, etc." - Buy a bed cover. $150-$2000. Mine were $200 and $500 and provided the largest "trunk" ever to keep those things you list dry and safe from wandering eyes. It just isn't climate controlled, but most of the time that's fine. A truck bed provides a great place to keep all the dirty recreational gear too!
