Went to blow out my drain lines from the pin-lock holes and they are totally blocked up. Is there a way to roto-rooter these out or do I have to figure out how to replace the lines?
On a couple of coaches I have had success with using a star shaped trimmer string as a roto rooter tool to open the drain lines. Your drain lines may be different size but worth a try/look. Those dirt/mud daubers love those drain lines.

Started from the bottom and was able to run about 6 ft of line in before hitting a hard stop. I'm assuming this is the T or Y intersection heading to the top two lock-pin holes.
Moved to the top and removed over an inch of hard crud from each hole digging down to what looks like a washer. The material through the washer is hard. Any suggestions for next steps? Remove these washers and keep digging around?
You might use the heavy gauge star trimmer string mentioned above chucked up in a cordless drill.
Here are the drawings for the pin and receiver assembly for a 2002 coach. I expect yours would be similar. I don't remember any washers in my assemblies.
The pins are shorter than the holes.

I used the trimmer line from the bottom. Got me about 6' to a hard stop.
I'm probably just looking at the bottom of the receiver and it looks like a washer...metal with a hole. It's appears the drain line should be center of the hole so I'll keep working on it. If it gets more complicated, I'll have to wait until fall/winter and I'll duct tape my way through summer.
