Actually your GCWR is much lower. 3.5EB, 145" WB 4x4 with 18" wheels is 16,100 pounds, with max trailer weight of 10,700 pounds. The 18,100 you refer to requires 20" wheels and tires. What's interesting if you look at the towing guide, page 19, https://www.rvsafety.com/images/pdf/FordTG2018.pdf, the 145" 4x4 3.5EB with 3.55 gears, Max Tow with 20" wheels has a higher GCWR and higher max trailer weight than the HDPP. 12,700 vs 11,600.




Your truck is still capable of towing that trailer you spec'd out, just keep in mind that it is a lot of weight behind the truck when reaching near it's full capacity. If you keep cargo(including FWT) to 1500 or less, you should be good towing it. That puts the trailer GVW at 8100 pounds, and about 1000 pounds on the ball. The length is good for your wheel base too.

 

Strange! I have nearly identical specs, with one exception, I have 20" wheels. My GCWR is only 16,100? What trim level is your truck and is it a 4x4? Mine is a Lariat 4x4.

My trucks full specs: 2018 F-150 Lariat 4x4 3.5L, 3.55 locking rear axle, Chrome package with 20" wheels.
Payload sticker 1600 lb, GCWR 16,100, GVWR 7000, (Have max tow package)

I am in the same boat looking to upgrade my camper to a larger unit. According to the formulas posted here, I should be able to tow a camper in the 7500 lb wet range.

 

I have the LX. Not sure what would account for the difference in payload. I wish I would have purchased a truck with 20 inch wheels. It seems that the max tow package doesn't help that much with GCWR if you have 18 inch wheels. My payload sticker does not include the GCWR. i am relying on the Ford Tow Guide.

We currently have a Winnebago Minnie 2201 DS that has a GVWR of 7,000 and a tongue weight of 620#. Our truck handles this trailer great. Really like this trailer but looking for just a few upgrades (extra seating, improved kitchen storage, improved boondocking capabilities, larger holding tanks, etc.) in a quality trailer. We don't want anything much longer.

Good luck on your search!

 

Thank you for your replay! I obviously misread the chart. I was giving the truck credit for the max tow package by looking at the lines with (7) next to the GCWR but realized we would not qualify for the maximum loaded trailer weight of 12,700#s because of the the 18 inch wheels. I am not particularly well versed in reading these guides but at a GCWR of 16,100 it doesn't seem like we realize any advantage of having the maximum tow package.

I am hesitant about this trailer now due to liability if we had a insurance claim for an accident and our trailer + truck exceed the GCWR of 16,100#s.

 

Here is a formula for the maximum length of trailer you can safely tow based on the wheelbase of your tow vehicle found in the book "How to Select, Inspect and Buy an RV" by JD Gallant who founded the RV Consumer Group.

"The maximum towing length of a travel trailer coach begins at 20 feet for 110 inches of wheelbase of the towing vehicle. For each additional foot of trailer length, add 4 inches of wheelbase." A second "common sense rule" offered in the book is, "If the length of the trailer coach being towed with a conventional fixed-ball hitch is over two times the wheelbase of the towing vehicle, you are probably living dangerously. (With fifth wheels, you can probably go as much as three times the wheelbase.)" pg 132 of the third edition

My F150 has 145" wheel base. So, using this formula, I can safely tow a 28'9" ft trailer. Using the common sense rule, I can tow a 24 ft trailer.

 

My truck is an 4x4 XLT with chrome appearance package. I am curious what option the Lariat has that the XLT does not have that would have that impact on your payload.

We currently have a Winnebago 2201DS that is 27 feet long and has a GVWR of 7,000. Would like just a few upgrades (additional sofa or chairs and better boondocking capabilities) while maintaining a similar length. Definitley trying to stay under 29 feet long. Really like the Outdoor RVs but they are heavy.

Good luck in your search!

 

Yeah thats where the "properly equipped" comes into play. If you read the fine print in the towing guide you will see that the maximum trailer weight truck is an XLT Screw 6.5' bed 4x2 Ecoboost with Max tow package and 20" wheels. If you don't have this specific optioned truck, the max trailer weights go down. For that you have to match what engine, gear, WB, cab configuration, and footnotes to find the true trailer weight and GCWR. It takes a while to decipher it, but compared to other manufacturers, it is actually a pretty precise guide.

Here's another kicker. Subtract the max trailer weight from the GCWR and see what is left over. Chances are the truck will weigh more than what is left over.

 

Yup, our '19 ORV Timber Ridge 24RKS weighs in at 8,740 lbs loaded & wet, with 1,100 lbs of tongue weight (full propane & 2 golf cart batteries).
Tall too, ours measures 11-1/2 ft tall.

 

That is the exact trailer we want (+one solar panel) but I am thinking it may not work with our 2018 F150 3.5L Ecoboost 4x4 Super Crew with rear axle ratio of 3.55, 145" wheel base, max tow package with 18 inch wheels has a GCWR of 16,100. Truck GVWR is 7,000. Payload after you add a full tank of fuel and one passenger is 1788# (working with 1500# payload to allow for 2nd passenger and dog).

 

PAYLOAD capacity only accounts for a full fuel tank. ANYONE, including the driver, in the truck counts as an Occupant. the Tires and Loading yellow sticker states: "Occupants and cargo should not exceed xxxxlbs.".
TOWING capacity accounts for a full fuel tank and a 150lbs driver.
