Rum, rum, rum@ 3,500 RPM
My E450 with V10 has a slight surging of RPMs at 3,500 and climbiing hills. Normal or something out of balance? New 8 months old 2015 chassis.

Home now and NO rum, rum, rum??? Climbed the I-5 Grapevine at 60 mph with the pedal to the metal and T/H on. At the start of the climb RPMs jumped from 3,500 up to 4,700 to 5,100. We stopped at Lebec Rest stop and when we pulled out onto the Hwy I was able to get up to 70mph and hold it all the way to the summit. Maybe the issue was resolved by giving it a good workout. She didn't seemed over taxed at that speed or rpm.
