A/C on rooftop and 8-17.5 tires

[Rachel1973]

I'm wondering if anyone has a 1973 Winnebago D20. And if you could give me some info on the rooftop AC.
Also is anyone else out there having a hard time getting their tires from Coker tire Co? I'm curious because I ordered tires back in March.
I did call them about a month ago. But this will I've not been able to reach anyone. So, I'm just wondering if someone might be having the same issue. i??
