Other years: 2015 —2016—2017

Welcome to our exclusive one-of-a-kind web page showing a quick preview of the best 2018 one ton trucks listed with diesel engines that includes the important rating details. Additional tow rating resources for other vehicles is found in the "Tow Ratings" menu above.

Important Notes:

1. The vehicles shown below are base models with the highest capacity, and without all the bells and whistles.
2. Therefore, any of the fancy truck's tow ratings will be less than what is shown below.
3. As truck weight increases, the towing capacity will decrease, such as going from a 4X2 to a 4X4 model.
4. Selecting optional gear ratio within the same vehicle will result in significant towing capacity changes. Examples of this are highlighted with green within the Ram trucks below.
5. We did our best to present similar trucks within each brand.
6. Realistic vehicle towing capacities (RVTC) are provided by RV Tow Check (RVTC set at 12% TW and 20% PW.)
7. For RVTC, we calculated additional load as follows: 5th wheel hitch—checked, cargo=150 lbs, two passengers=335 lbs.

WARNING! Never tow more than the manufacturer's published rating found in the vehicle owner's manual. Always ensure the hitch system meets the minimum towing weight of the trailer towed and it complies with the manufacturer's requirements.

Notice:
1. All rating information has been taken from published information provided by the manufacturer. Always verify vehicle ratings with the dealer. Ratings are subject to change by the manufacturer without notice. There may be slight differences between manufacturer's online views and PDF files.

2. "TWR" = Published, as in manufacturers' published information.

3. CC=Crew Cab, DC=Double Cab, QC=Quad Cab
