I towed a 10k trailer that is an industrial use box type trailer. It's a bumper pull, and I towed the first one from Corpus Christi to La Port Texas on level 3. No trailer brake controller on my P/U but I used tow haul mode and e/brake was activated. I towed the second one on level five and I got EGT that fluctuated between 960 and 1425. That scared me so I backed it down to level 3 and had no problems. Dodge 2008, 6.7, DPF deleted, Edge with attitude, 3.73 rear end, six speed automatic. Any comments or suggestions from the group on this information. Thanks.
