FAQ: "Can a F150 or 1500 or half-ton truck tow a fifth (5th) wheel trailer?"
As evident in the picture (left), we at FWS have determined that for typical RV use, most half-ton trucks do not meet the load requirements for the weight of these trailers. The GVWR and the GAWR will most likely be overloaded, and some driving conditions may be unsafe, even with the lightest fifth wheel RVs touted for half-ton trucks.
However, we have discovered one truck brand that may tow fifth wheel trailers up to 11,712 pounds and not exceed the ratings. That truck is the 2015 Ford F150 with the 3.5L V6 EcoBoost. The configuration that meets this requirement follows: 3.73 gear ratio, 4X2, 163.7" wheel base, SuperCab. With two passengers, the loaded vehicle weight is 5,388 pounds. The GCWR = 17,100 and the GVWR = 7,850. Especially for any half-ton truck, weigh it fully loaded without any trailer attatched and use RV Tow Check 2.0 to calculate the realistic tow capacity.
Obviously, there are several half-ton trucks towing fifth wheel trailers on the highway. One's ability to tow a fifth wheel doesn't prove exceeding the ratings is okay. The question that must be answered, is, "Are they towing a fifth wheel while not exceeding the truck's ratings printed on the Certification label?" (i.e. GVWR and GAWRs)
