What work were you doing? Anything that might cause this?
Sounds like you reversed the battery cables on pos and neg posts, so that blew the two 30a reverse polarity fuses.
Meanwhile the battery died but you still got juice from the truck battery via 7-pin.
Now nothing works because problem not fixed and fuses blown--check truck's 7-pin fuse, camper battery fuse, fix the reverse polarity, re-check the new two 30a converter fuses, see if the converter will now work to make 12v and recharge the camper battery.
