Couple questions on my 2001 f250 5.4

Just recently picked this truck up in a trade i made a couple months back and am still slowly going over it. So far it has been a great truck. Its the crew cab short bed 4wd with the 5.4 motor and it only has 144k miles on it. One of my questions is what would it be rated at for towing? There isnt any stickers on the inside of the door jams for me to go by and everything i've seen online states that its 12,500lbs towing but not quite sure if thats correct or not. We are looking at buying a new camper in the spring and want to make sure i stay under the towing capacity of the truck.

The truck does have a small shackle lift in the front and an extra block lift in the back to give it a little extra height and its sitting on some 305-70-16 tires. Would it make that much of a difference with the truck when towing or just regular everyday driving if i were to take the lift out and put stock sized tires back on it?

Im sure i will have more questions about this truck as i really like it so far. Especially now that ive found this site.

Do you know what your differential ratio is?

Also yes, removing the lift and going back to stock tires will make a noticeable difference in how the truck drives, and you will see an increase in MPG.

I was gonna check the ratio tonight. I didn't think the numbers i had found were quite right for towing capacity. Thanks for quick help.

Is there much difference in bumping up to a v10 in towing capacity? Some of the campers we are looking at have a dry weight of around 6700-7200lbs. Or if i switch out to 4.10's would that give me the greater towing capacity? Just don't want to be stuck with a truck thats almost maxed out every time we tow with it.

I tow at or above the rated weight with my 5.4L.

If you are not charging up and down mountain passes, are careful with your trailer loading and you take your time, your truck will surprise you.

V10 trucks of the same vintage are capped at 10k for bumper pull. The V10 adds about 3000# to the 5th wheel rating compared to a V8 with all other options the same.

Guess it just surprises me that my wife's 2005 hemi durango has pretty much the same towing capacity as my f250. Don't really have a whole lot of mountains around me so should be ok there. Will look into lowering the truck down to stock and getting stock sized tires to help it out a bit. Have looked into the 5 star tuner but didn't know if it would be that beneficial or not.
