Determining GCWR for a used truck
Hi, I'm a total newbie when it comes to the RVing world, but have been reading up for a while and am just about ready to purchase a used truck for towing a 5th wheel RV. The problem I'm running into must be extremely common, but I can't seem to find a clear answer on any forums, so I'm hoping to find some wisdom here.
When searching for a used truck, to determine the 5th wheel towing capacity, I need to first determine the GCWR. The problem is that this value is not listed on any truck stickers that I have seen and the owners never seem to know. I can get the manufacturer (I've been looking mainly at Ford F-250s) 5th wheel tow ratings, but GCWR is a required variable to know (it's pretty typical in my brief experience to see 2 identical trucks listed in the manufacturer's data sheet that differ only by ~500lbs of GCWR - the higher weighted one will not be rated for 5th wheel, the lower rated one will, which makes no sense to me). This tells me that I must know the GCWR with 100% certainty or else I am risking getting a truck that can't actually tow 5th wheel.
So, I'm wondering, when buying used, how does one figure this out? Is it possible to derive the GCWR from the GVWR and front/rear GAWR, which are typically included on the door stickers? Is the info in owners manual? Is there some other way to look it up? (Sorry if this question has been asked before, but I've looked in lots of places and cannot seem to find a discussion of this issue, but perhaps my search skills are lacking.)
