Questions
Truck is a 2018 Tradesman 4WD with the Aisin transmission and a 3.73 rear axle.
1. My old truck was a 2005 dually 2WD with a six speed. On the label for weights on the drivers side front door panel for the old truck, it had two numbers, one for a light load and a larger number for a heavy load. This truck has only one number and does not give numbers for light or heavy loads. Am I missing something as I do not see anything in the owners manual?
2. I'll be towing a 14k fifth wheel about 3k pin weight. What would be good tire pressures for this load?
3. I had, after reading extensively on the TDR, used Power Service in my old truck even before the articles in the 8-10/17 TDR and the 5-7/18 TDR in which they were recommended or approved by Cummins. Is the recommendation to use a fuel additive applicable to a 2018 truck since the emission system is very different from the 05 truck?
4. Truck has the built in trailer brake controller. I have hooked up the electrical cord but not actually hooked up to the trailer. I cannot get the controller to move to "Heavy Electrical" even after having a copy of the manual and following the instructions. Have tried twice and the instructions are not too involved.
Any secrets here?
Thanks in advance for any assistance.
