Regarding a separate black tank. That does not seem to be very common at all, but then you will have to pretty quickly learn to conserve, conserve, conserve, water. It's an art to be leaned when not camping with full hookups.
But for now go have some fun.
The last RV I had without a seperate black tank was my '69 Layton TT. A seperate black tank is standard on modern RVs. Along with the tires I would recommend a complete flush of the brake fluid. Brake fluid will accumulate moisturre. That is one of the biggest rerasons for brakie faillure. Moisture (water) can boil when hot and you can compress a vapor but not a fluid. The moisture will also permit corrosion on the internal brake parts. At that age I would also check the rubber brake lines. Enjoy with the family. We took our 3 children with us and some of the Grandchildren.
