Towing SV251 with 2009 F150 Lariat?

I am a RVing newbie and would appreciate some towing advice. We recently purchased a 2010 Surveyor SV251 that we have just towed for the first time on a 500 miles R/T shake down cruise. The route was mostly flat, and I was able to tow with no obvious problems. However, after reading some threads about insufficient tow vehicles, I am concerned that there may be something I'm not aware of. I am towing the SV251 with a 2009 Ford F150 Lariat with a 5.4 liter V8 with towing package (not the max towing pkg.). I am using an EZ Lift WD hitch. I have tried to use one of those online calculators to figure out whether I have enough truck to haul the SV251 but each time the result tells me that I am overloading my tow vehicle. I hope that is due to my not using the calculator correctly. So this past week I took my rig to a commercial CAT scale and weighed it. The scales showed that my truck, loaded for camping (half tank of fuel at the time of weighing), weighs 6840 lbs. and the SV251 with groceries, clothes, dishes, etc. on board and with empty water tanks weighs 4240 lbs. That comes to a combined weight of 11080 lbs. So my question is whether my Lariat is up to the job. I would appreciate your feedback and/or suggestions.

Welcome. Nice trailer you have there.

I think you should have no problem with your trailer. Its fairly light and I'd think that truck's GCWR would be well over 11,000, but you're doing the right thing in checking.

To start, what does the truck's door sticker say is the max tow cap and max payload and what's the manual say for the GCWR for your F-150?

Triguy - My truck's GCWR is 14,900, but I seem to read everywhere that Ford and most other truck manufacturers are greatly exaggerating their numbers. The Lariat sticker says the maximum trailer tow capacity is 9500 lbs. However, I don't know where to find the maximum payload. The Lariat's GVWR is 7100 lbs. Is that the same as the maximum payload?

You find your payload by weighing your truck before you're loaded for camping and subtracting that from the 7100 GVWR. That would tell how much you can load in the truck which includes people, gear, full tank of gas and hitch. Then what's left over will give you your truck's available tongue weight capacity.

You mentioned your truck's weight as 6840. Was that loaded, ready to camp and with the trailer hooked up? If so then you would be 260 lbs under your trucks GVWR.

grhodes50 - yes, when I weighed my truck it was loaded, ready to camp and with the trailer hooked up.

Gledelj, plug in your stats here: https://www.fleet.ford.com/showroom/...nvFifthTow.pdf and see what you come up with.

You didn't mention your cab and bed configuration.

I can't readily find the SV 251 online.

You are referring to the new standards. As an example, my TV is a 2008 Toyota Sequoia 4WD 5.7L. The sticker and manual that came with the car says my towing cap is 9250, but the new standard called SAE J2807 brings that to a more reasonable 7300lbs. The plan is for manufacturers to begin adhering to the standard testing process by 2013.

Your listed 9500lbs may or may not change.

So, here are the TV specs according to Edmunds:
Curb weight 5314
GVWR 7100
GCWR 14900
Towing Cap 9500
Cargo Cap 1760

Here are your loaded trailer's specs:
loaded weight 4240
Tongue weight at 15% 636


The loaded weight of the trailer is under the TV's GVWR and is good.

The tongue weight at a max of 15% of loaded trailer weight is also good and leaves you with 1124lbs for people and cargo in the truck. You might not have a tongue weight as high as 15% (10-15% is the range you want to shoot for with closer to 15% usually providing a better towing experience).

You can see that you have plenty of room in your GCW, as well (14900-5314-4240-1760=3586 remaining even assuming you fully loaded up that truck's payload).

You could go further and check the weights for both TV axles but I don't think its necessary. You are good to go my friend.
