Have 3 inch clerance/new truck/ need 6 for level fiver

Bought a Ram 2500 TCD and my 2014 Rockwood was 5" nose high when hooked to the ram. Pin weight on the rockwood is around 1400 - 1500 pounds, the setup was level on the old 1/2 ton truck with air bags. Hitch in the Ram was as low as it could go and the hitch pin on the 5er is a factory installed revolution, no adjustment. The Rockwood has no springs, it rides on torsion axels. Ordered and installed a 3" lift kit from Dexter for the trailer, everything is level again, air bags not needed on the Ram.
