No chemical, any toilet paper. Never dump before at least 1/2 full. Best to wait to dump until you arrive at the next campground. Driving will slosh the contents around, break stuff up, and help the dump process. More water in the tank is better. After a "#2 deposit", do a second "flush" after filling the bowl with water. Will help break up what's lying under the drop tube. Plenty of water is your friend. The system should be sealed and there should never be significant smells. If your toilet bowl will not hold water, it needs it's seal replaced or you will get smells. Most of the time odors are caused by a bad vent valve under a sink letting grey water stench into the RV. I don't think anything will extend the life of valves. They all quit around the 8-10 year mark. Valves are cheap and most are easy to change. Feel sorry for those with valves way back under the RV that require cutting holes in the bottom cover to get to them!
