Had a 2015 Ram dually reg cab 4x4 w/Cummins, Aisin trans, 4.10 gears and it was rated at 29.5K towing. Towed a 32' Excel 5er which weigh 15K loaded, truck did not know it was there, ride was decent enough. Had the SLT trim level and was about 12K less $$ than comparable CC. Didn't need a CC just me and the wife.
