We use Dawn Dish soap and same TP we use in house.
Special RV TP is expensive junk and not needed
We do everything in RV just like we do in house......no real difference between the 2 in my opinion except for the wheels.
I'll rinse down 5vr when we get back IF it has gotten really dirty or lots of bugs damp dryer sheets work well on front cap to remove bugs)
I'll dump fresh water tank/water heater.....refill next trip
Waste tanks..depends. If came home with stuff in them I'll dump at home. Otherwise took care of them prior to coming home
Our 5vr stays plugged in at home so we don't unpack other than dirty clothes/linens....then they go back in after washing
Fridge stays on.....milk and ice tea come out otherwise it stays full with normal stuff/freezer gets emptied
Camping is about enjoyment....not making things complicated.
Personally I think some Rvrs make it too complicated when it really is simple.
