This is one of the things that kept me from buying a 2500 diesel. When I looked at the towing specs I would get a 3,300 pound increase in towing capacity, for almost twice the cost of what I paid for the gas version.Problem you get into with 3/4 ton diesels is they have *hundreds* of pounds less payload than the gasser counterparts. The higher cost of entry, emissions maintenance woes, all add up too. And then folks don't buy base model 3/4 ton diesels, they get a lariat or whatever, which adds hundreds of pounds of doodads to the curb weight=lower payload even further. Nobody looks at their door jamb stickers!
The duramax 1500 payload numbers are abysmal though on the actual trucks, and honestly I would run a gasser half ton long before the small diesel if towing 7000lbs. Also, look at that GCWR on the duramax. 15000lbs. Only the lower rated 5.3 is the same, all other V8's with substantially higher GCWR.
Payload matters, as does GVWR and GCVWR. And at trailer weights over 5000lbs, half ton manufacturers probably recommend weight distributing hitches be used, too.
I moderate a facebook group of rv campers, and folks go out and buy a gladiator and want to tow a travel trailer with a dry weight of 7,000lbs. So, no propane, no batteries, and none of their shit in it, thinking "oh, we're within max trailer weight". It's purposeful ignorance and dealers and salesman aren't helping things. Dangerous.
I can't find a chart of curb weights, but for the Crew cab 4x4 1500 2021 with standard bed and LTZ trim, curb weight is supposedly 5100lbs.
if GCWR is 15000, that leaves 9k+ for towing still. Also if you buy the max towing package you can increase GCWR this to 16.8k or 17.8k (based on engine).
Also, for full size trucks they don't list a weight that you are required to use a WDH for, that is only for mid size and SUV's. For example the Tahoe is listed as 7k towing, but any tongue weight over 600lbs you need a WDH.
Long story short, any full size truck can pull a 7k trailer just fine, but I wouldn't do it with anything less.

It's a big can of worms, and one where education and research can literally save livesWow, I opened up a can of worms.
Appreciate all the info.
Diesel vs Gas is definitely a use case personal choice.. for me, I have towed my Jeep almost 30 times this year alone, totaling over 4000 miles, and that doesn't count hauling my camper without the jeep.... so it's worth it.My Silverado 1500 with the 5.3 & tow package tows it like a boss. It's not the best on a grades, but whatever. The 4 or 5 times a year I actually pull my TJ on my 18' steel trailer I just go a little slower uphill.
Yeah, if I did it all the time it wouldn't work. Handful of times a year for the TJ, we rent a bumper pull once or twice in the summer, I can get by.Diesel vs Gas is definitely a use case personal choice.. for me, I have towed my Jeep almost 30 times this year alone, totaling over 4000 miles, and that doesn't count hauling my camper without the jeep.... so it's worth it.
But yeah, if you only need the power a few times a year might not be worth the cost, though you kinda have to drive (and tow/haul) with one of the newer ones to really understand the difference.
Which manufacturer de-rates their towing based on altitude?The de-rating is for more than just performance, they de-rate your supported tow capacity due to overheating issues as Apparition mentioned. Multiple truck reviews recently on YouTube where they have half ton trucks overheating in the passes while towing.
Ford - look up the tfl overheating videos. Wasn’t the only brand they’ve overheated though.Which manufacturer de-rates their towing based on altitude?
I seem to inadvertently taken this thread off topic a bit. My original point to the OP was that altitude will not change a vehicles tow rating. It will affect performance. You will not be cited for being overweight if stopped or be held liable for an accident dependent on altitude. I have a Ford so knew that they acknowledged the decrease in performance but do not de-rate. It is on pg. 46 of their towing guide. I was curious if any brands actually de-rated their vehicles but I couldn't find any. At least we achieved in making the point that a tow rating as simple as what is claimed in advertisements.Ford - look up the tfl overheating videos. Wasn’t the only brand they’ve overheated though.
Ford is saying you need to derate yourself or you won’t make it up at that elevation as the owner of a piece of shit F150 3.5 ecoboost that sat on the side of I70 with a 7k trailer and an overheated truck I don’t care if I was legal or not.I seem to inadvertently taken this thread off topic a bit.

I think de-rate is more correct in this case.... overheating isn't what I consider a 'performance' issue like just going slower up the hill would be.It will affect performance.
overheating caused limp mode could not accelerate up hill.I think de-rate is more correct in this case.... overheating isn't what I consider a 'performance' issue like just going slower up the hill would be.
My family camping pal has the turbo V6. Alway overheats on the same climb every year. Not coolant overheating, turbo overheating that puts him into a failsafe to where he has to pull over & idle for 10 or 15 mins. Hasn’t been able to make that climb yet. I can make it, albeit at 35 mph. It’s pretty steep.Ford - look up the tfl overheating videos. Wasn’t the only brand they’ve overheated though.

This is what I have been wondering when @Apparition talks of overheating. I believe his F150 had the turbo.My family camping pal has the turbo V6. Alway overheats on the same climb every year.
