The official "Good Sam" RV channel is 13
But you are more likely to get good (Meaning useful) information on 19
I ran with both,, Only used 13 once.
19.. Way back in my trailer days had gone to Parents (no trailer) for Christmas. Freezing rain, black ice. Radio tells me of an overturned Semi I started slowing down.... Well I came to a nice safe stop between two cars (both in the Ditch, Both totaled) sheltered the occupants till the Deputy arrived to write it up... Took both families home.
Headed (years later) south on I-75 headed for Corbin KY... Did not make it as planned (Arrived a day later, safely) Radio said not one but two FATAL accidents up ahead.. Hit turn signal, exit and spent a nice relaxing night Wal-docking. Next AM no traffic jam.
Another trip I took the Detour the radio suggested.
I'ds say the radios paid for themselves.. each time. .
