I voted no....... my reason is when a post is in the 6.9 or 7.3 forums at least we have a 75% chance the owner has posted his request for help/advice in the right place.
I work on FTE also and they have them combined....... continually having to search a posters profile for a truck description gets very annoying and wastes time of those willing to offer assistance.
If the forums are combined then it should be mandatory that an up to date signature with vehicle(s) info be shown and reference to the exact one when posting questions/info.
Engines are not the only criteria for the 2 forums...... there are numerous body, electrical, fuel and other system differences to take into consideration too.
