Oh Bordercollie! I'm sorry you went through all that. It's always such a gamble buying an older RV. I knew with a 1985 with 47K miles on it, there was a lot of sedentary times and I know that can be the worst for a motorhome. So far, I'm doing okay. Had to replace the water pump and then found out that there was another thing (outside spout to drain the potable water tank) that also needed to be replaced. Took care of that myself (and largely, much of the water pump was my doing, too!) and that increased the water pressure significantly.
Then I decided to give the hot water heater a go and turned it on with the electric switch. The valves were so tight from years of not having been moved to the open position that I thought it was just broken. But now they move much easier. In fact, one of them drips water from time to time. I can always tell cause the water pump takes much longer to kick off. It's like, "Ut oh. Another water leak somewhere!"
It's an adventure, and I haven't even hit the road yet. God be with us all.
