I have a 2005 Dodge 3500 SRW pulling a 5th wheel with 2500 lbs of hitch weight. Trailer sets the truck down quite a bit so I installed a set of Timbrens, they hold the truck up fine, but seems to transfer a rough ride back to the trailer. Is there a better option like air bags to use in place of the Timbrens? Anyone had any experience? First time Cummins/Dodge owner.
