Things kids should bring on a road trip are coloring books, tablet, snacks, clothes, blankets, sickness bag and trash bag, diapers if they wear diapers, wipes to clean hands or change diapers.
If the child is in a car seat then you should also bring car seats along.
Anything that your child may want or need during the road trip you should bring and if the child is potty trained you should stop often to allow them to use the toilet and also to allow the kids a break.
If partly potty trained then you should bring a potty along and pull ups.
If the child is not potty trained then bring enough diapers to last the road trip.
Rather than stressing yourself out about frequent stops, build them into your road trip itinerary.
Kids shouldn't be in their car seat for more than two hours at a time.
Make frequent pit stops for food, bathroom breaks, diaper changes, and to get the blood flowing.
Things you can stock in your RV kitchen are evaporated milk, powdered milk, rice, canned beans, dried pasta, ramen noodles, jarred pasta sauce, canned tomato sauce, canned tomatoes, canned tuna, canned chicken, coffee creamer and coffee.
Also stock dish soap, dish towels, plates, cups, spoons, forks etc.

Grilled chicken and mashed potatoes and gravy also make for good camping dinners or even some Chili cooked over a campfire or on your RV stove.
Things you should keep in your RV are toilet paper, sewer kit, sewer hose, drinking water hose, other garden hose for flushing black water tank and sewer hose, leveling blocks, water pressure regulator, chemicals for the RV toilet, electric adapters, surge protector, food and other toiletries such as soap, bath soap, hand soap etc.
You should also stock food that you will eat when camping.
RV toilet paper is not really necessary although RV toilet paper is designed to break down easier in the RV toilet so it won't clog the black water tank like some other toilet paper could.
You can use regular toilet paper in the RV toilet as long as you use single ply toilet paper and not the thicker toilet paper.
If using regular toilet paper in the RV toilet just be sure to not use too much of it and use chemicals in the RV black water tank to help the toilet paper break down easier and faster.
Also be sure to drain the black water tank often so that it does not become clogged.
I've used regular toilet paper in my RV and it has never been an issue.
The RV toilet paper costs more and to me is not worth the extra price.
Never bought RV toilet paper and always have used regular toilet paper that is septic safe.
I just always drain and flush out my RV black water tank before it gets too full and never had any issues doing so.
