Im not sure about RV's but for me and all of my auto's/Jeep I usually go with the 50K mile mark for Tranny + rear end fluid.
That 97,500 / 150,000 miles just sound too long to me - esp if your towing.
But perhaps these RV's are Heavy Duty enough they can go that long.
What does the color of the Tranny fluid look like? If it looks like new I would keep going till 50K.
The rear end should be fine for at least 50K IMO. Unless you go though 3+ foot water - that could suck in water. But my jeep not the RV.
