Replacing front springs on 2000 WorkHorse chassis

Well, I changed the bags in my last Itasca but was not totally satisfied and I have always felt that this RV has sagged in the front even when the airbags were working. They just didn't seem to do the job of leveling it. I have read that other people have had success with the new steer-safe springs that are matched to the front end weight of the RV. I just never have liked those airbags and it seems like a poor way to make up for springs that are too weak for the job.
