My brother and sister in law have this idea to rent a big RV and go across the country next year. I think its sounds neat but not sure if its feasible with little ones. My dd will be just 3 and theirs will be 1. Anyone done this?? Can you even put carseats in an RV - do they go up to the table so kids could color or do other things? My main concern is entertaining two toddlers on long travel days.
