I have 3211 so lets see if we can fix something before using wty. First - no shore power. If gen power works probably transfer switch is bad - Open bed storage and remove thin wood cover and open plastic box on right side (with shore power cable disconnected.) It is about six inches square and three or four inches high. If you see badly discolored wire connections that most likely bad.
If no 110 shore or gen - reset all breakers - behind plastic door, front left side of bed storage. TV and micro not worth looking at until 110 working.
Steps usually much more difficult and expensive - could end up as wty item.
If nervous about doing things - PM me and I'll walk you thru everything. Grew up in Huntsville so I gotta help.
