Bumping for Newbs

11screw50

Can you add a clarification to the OP? If you have a 2015+ with the 5.0 or 3.5EB (or 2.7 with payload package), you need to check GCWR as well.

Here's why: assuming the weight of my truck is GVWR-Payload, it's 5182lb (7,000-1818). Tow Rating is 9100 and GCWR is 14400. So after hooking up that 9100lb trailer, I've got 118lb for WDH and me before I hit the GCWR. But from a payload standpoint, 13% of 9100lb is 1183lb and my payload is 1818lb. Plenty of payload left for WDH, me, wife and a couple bikes (plus all the crap that is always in the truck). (Of course, if you put four adults in my truck, yeah, payload is a problem but I'm over GCWR before anyone even gets in the truck so...).

So even once you figure out how to stay under payload, you need to check the other numbers as well (and for the guys with big tow ratings, they need to check against their hitch rating too.)

Since my OP has limited room, I put in a note and linked to your post.

Adding a few notes of clarifications that were discovered between the posting of this and now. The receiver weight rating, it will state maximum tongue weights with WDH. You do not need to subtract the weight of the hitch from that number, it is the weight on the ball itself. So if you have Max Tow with a 1320 pound WDH limit, that is 1320 pounds directly on the ball per SAE J2807. Another thing discovered is that GVWR are not the same between trucks of the same cab and trim. A 4WD Screw 5.5' bed 145" is 7050, while the exact same truck in 2WD is 6750 pounds. Ford still plays the GVWR game, they could have easily given the RWD the same GVWR since the only differences between the frames are the mount points for the transfer case and front diff.

One other thing to note, make sure when you purchase your WDH that you have the proper spring bars for the tongue weight of the trailer, don't go too heavy, 1200 pound bars for a 700 pound tongue wont provide enough sway control, and getting them tight enough to provide sway control can unload the rear axle too much. Get bars that are minimum 80% of the tongue weight. For 1000 pound bars, 800 pounds works well, 1200 pound bars 960 pounds is the target, This will allow for enough tension to provide sway control as well as proper distribution of weight.

Also if you are shopping for a trailer don't assume any formula is really going to be accurate much less dry weight means a thing.

I recently found what I thought was going to be my next TT.

Listed Dry Weight - 5546
Listed Dry Tongue - 515
GVWR - 6995/7495
​​​​​​
Real World Tongue Weight (Loaded and with Freshwater) - 1200 lb + (17%).

Research, research, research!
