2015 Yukon TT Weight Help

Hello all, I'm new here and we are currently in the search for a "new" TT for the family. Mostly looking at the used market as it seems like a good place to start out to make sure everyone enjoys things before upgrading. :)

I've done a fair bit of research on what is the right weight for my vehicle but vetting it out with the experts here is what I'm after. Below is what I know about my vehicle and what I'm thinking in way of possible weight of TT.

It's a 2015 Yukon minus the heavy duty trailer package. We have the 3.08's but the Service Part Description sticker shows the vehicle came equipped with the Oil and Trans cooler. Max payload sticker shows 1500lbs and the hitch show's max tongue weight of 1000lbs. I'm figuring approx 500lbs of gear in the Yukon leaving 1000lbs of payload (tongue weight). Max towing capacity is 6300lbs.

TT's we're looking at have a tongue weight of around 500lbs with empty weight of 5100/5300lbs. Assuming full of clean water we'll probably be around 5500/5800lbs.

One concern we have is we're located out in Denver, CO and with a gasser I have heard you want to play it down some due to high altitude and naturally aspirated engines struggling a bit up here.

My couple questions are is the "high altitude" concern legit and the other being is the dry weight of what we're looking at seem reasonable or should we look at smaller/lighter units?

Thanks in advance for all the helpful insight!!

  • Thanks guys!

    Can't take the truck back now so we're stuck with what we have.

    Campfire - When you say limited in how far/long can you elaborate on this? Same thing with "hating" it?

    I have two small children, wife and a lab. I could probably see after a couple years upgrading anyways if it's something we all enjoy doing. Purchasing a truck to specifically pull a fifth wheel or larger TT wouldn't be ideal right now but I definitely could see going down that path after a couple years.

    Thanks again for all the help!
  • I'm not concerned about the gears. Even if all the numbers work and you stay within specs, you'll be close on all your numbers. In my experience, you'll be fine but you'll be limited on how far you tow and how long. And being in mountains, well that would be a big limitation. I've towed two different combos close to my limits. Its worked fine in the flats of WI, but I would never have taken either of those combos through the Rockys. That said I think you'll hate it. I'd be looking at trailers at least 1000# lighter.

    You also said "family". How many? Keep in mind the kids grow and so does the amount of stuff they bring. Today you might keep within the payload numbers. Two years from now you might be over. Something to think about.
  • The 3.08 axle is a dealer killer in my book. This is a highway axle ratio and not a towing axle.

    With that axle ratio, I'd keep my wet and loaded weight under 4500# as a max.
  • Can you take the Yukon back and get one with the NHT package or better yet the Ford Expedition with Ecoboost?

    RV tow ratings for half tons are typically limited to tongue weight or payload. But your limit will be performance/perception bcause of that 3.08 gear. Even thought the 6-spd trans really helps, you'll be cruising on flat land in 4th gear at 2500rpm and down to 2nd gear for those mountains at 5000rpm. Truck will be fine, but will the family?

    The typical RVer adds over 1000 pounds of camping stuff over dry ratings based on a survey done in the past. So 5k dry will be 6k loaded, more with full water. So you'll be right at the 6300 pounds of tow rating and whatever your GCWR is.
