But most RVers have 250/2500 or 350/3500 class trucks - gotta love those ford ads about having best in class towing/payload.

250/2500 and 350/3500 are not truck classes, they are just model numbers and their capabilities can mean anything the manufacturer want them to.


I also think many put too much weight on this J2807 thing. It is just a standard set of tests to come up with a tow rating. It does not mean that a J2807 truck will outperform a non J2807 truck with the same load. It also does not mean that a higher J2807 truck can outperform another truck with a lower J2807 rating. For example, look at the 2.7 Ecoboost and 3.0 Ecodiesel as an example. The 3.0 Ecodiesel is J2807 rated per Ram to tow more than the J2807 rated 2.7 Ecoboost yet the 2.7 Ecoboost has been shown numerous times that it will out perform the 3.0 Ecodiesel loaded or unloaded by a considerable margin.

It also doesn't mean that any manufacturer is fluffing their non J2807 numbers either. For example, a 2011-2014 F150 Crew Cab 3.5L Ecoboost 3.55 was only rated to tow 10,000 lbs before J2807. Now the same truck is J2807 rated to tow 11,900 lbs in 2015. So how is the non-J2807 rating fluff when it is 1,900 lbs less than the J2807 rating?
