How much weight do you tow with your GAS truck?

I donít want to have this turn into a gas vs diesel thread. I donít have a diesel, and donít want a diesel, and not interested in how much your diesel tows.
This evening I was looking at market place online and seen a nice looking 5er with a 12000 UVW. I know that donít mean anything, it would probably be more like 15000 by the time I loaded it.
Not that I want to buy this RV, it got me wondering how much are people really towing with there gas trucks?
When I bought my truck I figured it would be good up to 10,000 trailer. I bought a F350 6.2 gas, 4x4 Sb with 5th wheel prep, 4:30 gears and 4114 CCC. I think it was rated to tow 18,000, not that I would try. But could I?
So Iím curious how much do you feel comfortable towing with your gas rig and what truck you have.

Just rough figures(3100 pin weight gestimate), youd be ok on weight...but man thats a beast. I would want disc brakes on the trailer for sure.

Everyone has different comfort level when towing. I see some people max out all ratings and I don’t see why that’s a problem.

Been towing around 13 000lbs since 2014 with mine. No reliability issues. It works hard up long inclines over 5 to 6%. It has no issues holding 5000 RPM for several minutes although I understand it rattles many people's nerves when doing so.

If I had the newer GM 6.6 gasser I'd be tempted to do up to 16 000 lbs. Seems like the big Ford gasser does well power-wise. We shall see how reliable it is over time.

with my '19 ram 1500 4x4 ccsb 5.7 with 3.92 gears, I tow our 6000# 28' long travel trailer. the truck tows the trailer easily and the 8 spd is very smooth and it is easy to get up to speed onto the freeway. I wouldnt go with a much longer trailer with this truck..also the cargo capacity is only 1324# so have to pack light. my truck has great brakes and our trailer has 4 wheel brakes so plenty of stopping power. I set cruise for 68-69 and get 8.5-10 mpg depending on the terrain.

By saying we drive 'conservatively' does that mean 'slow'? 8,500lbs will wag the little dog in this case in my experience.

AFAIK this is a 5th wheel he's pulling. I have never heard of a 5th wheel setup causing uncontrolled sway.

I have a 2020 f350 with the 7.3 gas and 430 gears. I pull a 35' montana 5th wheel gvw 15000 lbs. Camper loaded weighs 135000. The truck has a 4229 lbs carrying capacity. I gross out at 21000 lbs.

I get about 8 mpg and have no issues with the power. The truck can keep up with traffic on any hill, although I keep the rpms around 4500 rpms. The truck redlines at 6000 rpms. At 6000 the truck will gain speed going up any hill, but sounds like the engine wants to come flying out of the hood.

Previous truck was a 2011 superduty with the 6.7 diesel. I got 10 mpgs. Truck was quieter going up hill because rpms were at 2500. The gas truck will do fine on the flats at 2000 rpms.

I use tow haul mode because it really helps to slow down going downhill by downshifting. Just get used to high rpms when downshifting. I would definitely do gas again.

Previous gaser was a 2018 Ram 6.4, 4.10 2500. TT is 31' @9600 lbs. Did a 3000 mile 28 day trip in 2019 through WA, Ca, Ut, WY, MT, NV, CA and back to Oregon.
Although I never stalled on any grades, being about 4,000' most of the time and crossing over the Tetons @8431' and 10% was the deal breaker. 1st gear wound out tight, then the downhill portion where the brakes got hot at the end when I rounded a corner to see a Stop sign for road construction.
MPG's sucked so bad on that trip that I needed to always be thinking about my next fill up.
Remember you lose 3% of power for every 1,000' of elevation increase.
410 HP was cut to about 310 hp.

I had a 12 CTD prior and hated the regen and short oil change life, so I opted for a gas truck after 6 years. Needless to say i went back to a CTD in late 2020.

I find the EB and better mpg's just as advantageous as the extra power of a diesel.
I can't imagine towing 12-15,000 on that same route with a gaser again.

I'll admit that the 2018 66RFE gear spacing sucked bigly and that it was the main reason for the constant over shifting. But the poor mpg's was the worst part of the gas experience. It was the fact that I used more gas, it was that even with a 31 gal tank the range was short. Out in the big stretches of travel I found my self filling up way before needing to just to be safe. Not knowing where gas stations are and whether they're open or if open can I fit in was the worst part.

I suppose if you're traveling a lot in the southeast or northeast parts of the US you have more gas stations. Out in the west they're spread further apart.

Not trying to go diesel vs gas, but just pointing out why I gave up on gas.

IMO a gas truck can tow just as much as a diesel truck but with different attributes. You may not be able to go as fast but you will get there.

The only issue is not to exceed any of the specifications for GCWR, GVWR and GAWR for the truck you have.

When I first started working a 6 yard gravel truck generally had a 6 cylinder gas engine. It was a big day when they started putting V8 into them.

I don't think a gas engine can tow as much as a diesel engine. A diesel engine is a lot heavier with more robust parts. I think a gas engine is a lot easier to blow up than a diesel engine.

But within reason a gas engine is perfect for a lot trailers but if you want to tow a 35,000lb trailer you better have a diesel.

It looks like we are getting into the gas vs diesel again. I agree diesel will tow more then gas.
What Iím asking is how heavy do you tow with your gas rig.
I see a few replies from ram 1500 owners. That is what I had before I bought this truck. It was a great truck! Plenty of power, towed great. But I found myself close to or going over the 1387 ccc a lot. I seen one post that I think he is pushing the limits but Iím not here to judge, just curious
After 135000 miles and planning a long trip I upgrade trucks. A little over kill for the 195RB we have with a 5500 GVW. But if I want bigger in the future I can.
