I'm trying to get some realistic info on where I really sit with towing capacity and my rig. I have a 2016 f150 XLT 3.5l Eco....super crew with 157" wheel base. We have the tow-mod. My concern is it has a 6" Pro Comp lift and .18" wheels...tires are 275 65r18 all terrain. We are starting to shop travel trailers, and all I have ever hauled is a 1200lb tent trailer, which is nothing.
The trailer we are looking at is a 30' RV with a dry weight of 5615lbs, tongue weight of 645, and gross weight of 7000.
With my current setup, what realistic and safe tow capacity am I looking at?

What does your Payload sticker say? Have you read any of the very detailed threads on this section of the forum?

So you're running a 6" lift with stock size tires? If so, why the lift? The truck will still pull the same amount of weight with it, but the higher center of gravity may make it more difficult to control.

Apologies, it was 2am when I posted that and didn't even get all the information right. I accidentally pasted the stock tires in there. It actually has 35x12.50r20lt 121Q ironman tires on it, and the 3.55 axle ratio. I'm having trouble finding info because there is no vehicle payload sticker that I can locate. It has the 7050# GVWR package. I've tried searching the forum and am not finding any detailed threads on the newer 3.5l towing with this type of setup. The reason I posted was to see if someone more knowledgeable on this could help me with realistic numbers here.

Found my payload sticker. It was under some protective cling wrap. It says the vehicle max weight is 7050 and not to load more than 1850 in the truck itself. I'm still wondering how the lift and tires changes that. I talked with Ford, and they said I have the tow package putting my tow capabilities at about 9k lbs rather than the 12k which would come with the Max-tow package. They weren't positive on what restrictions the lift adds to that though. Dry weight on the RV I am looking at is 5200 lbs with a 7000 max. So by their recommendation, I should be well under since I won't be max loading the RV up to 7000lbs. Still I'd like some peace of mind there when RV shopping, and some more experienced advice on running with this lift....if the 3.55 gear ratio will be ok, or should I consider changing to 3.73.
I was also trying to edit the title of this thread to get more info for anyone skimming the forum, but when I save changes, it doesn't change.
Thanks for any help....this is all new to me, and bottom line my concern is being safe of the road.

Now you know your Payload. Did you read any of the threads? 1850 minus you and passengers minus weight distribution hitch minus everything you added to the truck minus everything you load in the truck.

Take result, divide by .13, and that is the max loaded trailer weight.

Read quite a few, and like I stated before. None of them that I find on search deal with the parameters I am presenting here, or address the questions I brought up here. I can calculate the towing load. I'm asking about the lift and tire impact.

from what i understand the added weight of your tires, wheels and any lift components should also be subtracted from payload. also heavier tires or wheels = more rotating mass which may require upgrading brakes which isn't a bad idea with towing a TT. specific drivetrain specs will still be applied to you magic sticker inside your door jam and that will give your limitations according to ford lawyers err engineers. there are several threads you can read until your eyes bleed about calculating weights and capacities.

My understanding is that heavier tires and wheels impact the total weight of the vehicle, which means by default you have less payload, because the max weight minus the actual weight equals payload.

If you trailer weighs in at 7000 loaded the 640 lb tongue weight is too low. 7000 lbs x .13% is a 910 lb. tongue weight. So 1/2 you payload is already gone not counting the lift kit and tires.
