I need some assistance with my towing number calculations to see if I'm calculating correctly, and if I'm over the limit anywhere here.

Truck Numbers (F150 Ecoboost SCrew)
Payload (from door sticker): 1348
Curb Weight: 5615
Max Trailer Weight: 9600
GCWR: 15500

Trailer Numbers (Winnebago 28DDBH)
Dry Weight: 6740
Hitch Weight: 760
GVWR (I'm not going to load this much): 9560

Towing Assumptions
Passenger load (family + clothing/gear/dogs): 545


Calculations
Remaining Payload (truck payload - hitch weight - passenger payload): 1348 - 760 - 545 = 43
Remaining GCWR (GCWR - trailer weight - truck curb weight - passenger load): 15500 - 6740 - 5615 - 545 = 2600


This is assuming some of the numbers are on the light end, for example I haven't added the weight of water if we were to tow with that, etc.

My concern is if I am miscalculating anything, and more importantly, if I'm getting into a dangerous situation with towing this much. I do have the options of moving to a 2013 F150 with Max Trailer Tow package and 1500 payload limit on the truck, but I'm not sure if that's necessary or beneficial.

Any advice would be great, thanks.

AKSUNDOG, First use your max weight from the trailor to calculate. This will give you closer to real world weights. I would go to the Max Tow w/1500 payload to be on the safe side or even max tow w/HD (8200 GVW) also.

I figured that would be the response...

I can go for the max trailer tow package with 1500 payload, but the HD would be a pain because I understand that to require the longer truck bed, no? I'm just squeezing into my garage in terms of length at the moment, and you don't want to leave you truck outside during the winter in Alaska...

Thanks for the feedback.

You are right about the HD package but you can get a 145" WB SCREW 4X4 Eco with 1900 payload GVW of 7650. This is the Max Tow. Ford Spec sheet off of there website.

RV trailer with a GVWR of 9,560 pounds is probably going to gross over 9,000 by the middle of your third trip.

Your dry hitch weight is 11.3% of dry trailer weight, so you'd better figure at least 12% wet and loaded hitch weight. 12% of 9,000 = 1,080. That's 320 pounds additional hitch weight you didn't count on. You don't plan to carry any tools or extra fluids, or a floor jack in case of a flat on the trailer? Bad decision. You don't plan to add a spray-in bedliner? So bottom line, you're going to be overloaded.

The extra 500 pounds payload of the max tow package is absolutely required, and the HD payload package is probably needed if you don't want to be overloaded. You can get Max Tow (but not HD Payload) on the SuperCrew with 5.5' bed. I suspect that even with max tow in a shorty bed you'll exceed the GVWR of the F-150 by the middle of your third long trip. IOW, you'll probably be overloaded

Going from a 1350# payload to 1500# is only a 150# jump up. Hardly worth the trouble and cost.

Before doing anything drastic and expensive I'd empty out the truck, move everything non-living into the trailer, which has carrying capacity, and then see how bad your numbers are. With care, it might be doable with what you've got, but you'll want the scale numbers to be sure. And you'll have to watch it in the future.

Thanks for all the feedback. I decided to trade in the truck and upgrade to a 2013 F350 Powerstroke. I think it cured all my towing and payload concerns.

Similar to my daughter's experience recently. She looked and looked for an F-150 SuperCab with HD payload package. There were none in captivity. And even if she found one, it would have the 8' bed. She wanted a shorty. So she wound up with an F-250 SuperCab shorty. It has more payload capacity and more towing capacity than the F-150HD, and it's available as a SuperCab shorty. So she's a happy camper.
