If the springs have sagged or flattened from years of being loaded up (these are truck chassis and few trucks are fully loaded 100% of their life) consider taking the MH to a truck spring and suspension speciality shop and have them re-arch the springs and add a leaf to them. In the long run this is the best thing to do. If you have add on air bags (Winnebago installed 3T kits on the Views from the factory) then make sure they stay inflated to a minimum pressure (probably 40 psi or so) otherwise them will fold and wrinkle and leak. Will last much longer with air in them ALWAYS.
