Suggestions for family games while RVing/Camping

I camped often with 1 and 3 year olds. Get a bike trailer and you can go for family bike rides. Honestly, we do try to camp at kid friendly campgrounds. If it doesn't have a playground and either a pool or lake/pond/creek we would go someplace else. We all like to explore the new campgrounds together and the kids like to make new friends on the playground.
