OBS tow question

Im in the market for a 5th wheel. i bought my truck with the intent to tow a tt or 5th wheel with it. The truck is stock to the paper air filter for now. My "plan" is to have stage 1 injectors intake tune exhaust intercooler gauges with rear air bags and a good brake controler. But here is my question, am I still asking too much of my truck? The unit im looking at has a GVWR at15500lbs. Dry weight is 12999lbs. From what I can find my tow rating is 10k. Am I really going to need more truck to move this pig down the road safely?

Oh and ive got an auto with 3.55s so those are going to have to go also

The GCVW of your truck is 18,500 w 4.10 and 15,000 w 3.55
Your truck EMPTY weighs a MINIMUM of 6500. then factor fuel, you, family, gear etc you are 7000-7500.

Subtract your truck weight from the CGVW and that leaves you
11,500 on the high side and 7500 on the low side.

I think you are asking TOO much looking at a 5th wheel of that size.
YES your truck will pull it. It will NOT like it, nor will you

My trucks CGVW is 20k(4.10s and stick) and I grow out at 20-22k frequently. But I also have bigger injectors, exhaust, intake, chip, etc and it does well, but it aint no rocket ship

Looking for Blue 40-20-40 seats. PM me !!!!!!!

I've pulled 19,700 and my truck is bone stock (well it was when I did that) down to a down pipe only, look into gauges, better gearing, and just make sure that's what you want, your truck should pull fine, won't be the fastest on the road but won't be to bad either

Gauges, trans and egt will be a must if im towing anything but local. With that much weight the 4:10s will be replaced prior also.

I guess my question is my truck comes with a factory rated tow capacity. Im gueasing that was based on factory equipment. So if I upgrade things like sticks, cooling, braking , gears and or transmission, should in theory change my trucks tow capacity? Or is that based on a structural ability of my truck?
Im just having a hard time swallowing that my f350 7.3 diesel has about the same factory tow capability as a current f150 ecobust

You can build it up to tow that weight but in some states you could be considered overweight esp when you find out that the 5th is much heaver than what the salesman tell you.

Look up OLD Outlaw posts and what all he's done..we build it up for him and he's towing Heavy.

After a regear you can tow that much now prob. Like previously said you will be slower off the line than a new truck but I've run 70 all day with that kind of weight just fine. My state does not bother non placard rigs. And I hold a cel and health card so I don't worry bout it too much with a good brake controller I've not had an issue stopping either and I've owned new pickups before to compare

Your truck will handle that weight just fine now, but I would want 4.10 gears to make it easier to pull.

I pull a 9000 pound horse trailer almost every weekend with a 3.73 rear. Twice a year I pull 18-20k pounds hauling hay.

Nothing can ever be done to change the gvrw of any vehicle, even putting in F550 axles and suspension.
