Sounds like you're still not looking at the ignition module even though they give the symptom you're talking about, and are known problems past and present. More so on Motorhomes due to lack of good Ford engineering for air flow.
Ford TFI modules were a problem when mounted on the distributor but the F53 MH chassis has the TFI mounted on a heat sink on the firewall. There is plenty of air flow there and the TFI has very little problem on F53s. My 23 year old OEM TFI is still going strong.

Tell that to my old '96 460 Cruise Master. Mobile mechanic went right to it, and said it was one of the most common problems on the F53 after it left the factory.
