I've talked to several people in the industry about a more realistic tow test using an average family of 4 with 2 teenagers and a few hundred in the bed and a max frontal area but because it would result on smaller numbers everyone has said it would never fly as marketing would kill it.
Honestly I think the test they do, especially the 11 mile Davis dam test is much harder and more demanding than the normal person would pull. Over 3000 feet of elevation over a short 11 mile stretch going a minimum of 40 mph. So for example, if the 2020 Silverado pulled the 9500 lbs through that stretch of elevation and demand without any issues, I would say that pulling 7000 to 7500 lbs would be no issue. And they actually use a 150 lb passenger as well on their runs.
But they are not pulling a wall through the air. As has been said, for RVs, tow weight is basically useless as you will not hit that number before running out of payload.
Tow weight is fine if you are pulling a flatbed full of lumber. Build a front facing wall from that lumber and the result is totally different.

Yeah, from what Iโm reading, most new trucks are tow rated Based on j2807 standards. So if a truck is rated for 10,000 lbs then that means it passed every single test towing towing 10,000 lbs.

If it actually weighs 6000# dry. Mine was around 300# more than stated dry weight. I scaled it on the way home from the dealer. On a trailer that size, I wouldnโt be surprised to see 500# or more.
Thatโs understood which Iโll keep into consideration. I gave myself wiggle room with the weight numbers I stated above.
Sounds good. I have the same truck you are looking at and I doubt if you would have any problem toting a 7000# trailer.

Like many, I am confused about my truck's towing capacity. I've read every word of this thread twice. I figure, the best thing might be to put on my own truck's specs and lean on the experts on here for help.
2009 Dodge Ram SLT Quad Cab 2WD 4.7 V8
Gear Ratio 3.55
GVWR 6,700
3,700 front; 3,900 rear
Payload 1,681 - I'm assuming this is my payload as it's on the sticker inside my door.
95% of our travel will be somewhat local and on flat roads; however, we do want to take the occasional cross-country trip. We'll never be in a hurry as we're teachers and anticipate these rare trips to be over a good length of time.
What would be a comfortable dry weight "max" for a travel trailer? Thanks in advance. Ty
