1997 Class C Winnebago, 47,000 miles too old to buy?

I loved my 1987. However maintenance costs were $0.25 per mile. I drove it 200,000 miles. It was shared with my brother. In the end I purchased my own RV and he bought me out. The repairs started looping--for example the power steering had to be fixed in year #2, and fixed a second time in year #8.

Parts became an issue for the chassis. The house part was reliable with only the water heater board going out. It had 125,000 miles on it when purchased.
