I think you're right about staying with the 5,600 lb. standard Ford spring. My son rented a 2016 F250 CC, 6.7 last Dec. to pull his camper to Florida and he said it was the most comfortable ride he'd ever been in but I think it had a lot to do with the seats. I guess he meant including cars too but not sure.
Taking the bumper off might have been his way of trying to justify the cost or making me believe the cost was justified. I haven't even looked at mine to see how it'll have to come apart but I'll check the youtube video out and if I don't have to use a compresser it'll icing on the cake.
