Which house has the most overall display units?
I would like the house with the most weapon racks, wall plaques, display cases, mannequins, and book shelves. Which house has the highest total combined of all four types?
Solution 1:
According to this chart on UESP The windhelm house has the highest amount of overall display types, with 12 bookshelves, 2 shield plaques, 7 weapon plaques, 1 weapon rack, 7 display cases, and 3 mannequins.
