My BIL has a 04 F250 and a 05 Jayco Eagle 325BHS 5th Wheel, he installed Firestone Air Bags on his F250 because it squated too much for him.
He also said his F250 would bottom out when going accross railroad tracks and such.
After installing the Air Bags his truck runs level and he said it rides much better.
