Can I Tow This with my 2015 Double Cab

If you are bound and determined to do it then you need to buy load range 'E' tires at the minimum. And don't oversize the tires, that will raise your rear gear ratio from 3.08 to something in the 2's. Oversize tires rob power.

And make sure you are insured to the hilt because if something happens (accident) then they are going to be looking to assign fault and any under-rated equipment could be a problem with insurance adjusters looking to absolve their companies of paying claims.

There's can you do it? Should you do it? and Is it legal to do it? Physically, your truck can tow that all day long whether you regear or not. It may not like hills or headwinds but it will do it. Whether you should do it is more of a personal choice based upon your own perception of risk. Some of us here would and some of us wouldn't even consider it. No matter what you decide, your truck's GCWR is 12000lbs. This is whether you re-gear or not. Re-gearing doesn't put a new sticker on your truck. If you decide to take that risk, know that if there is a serious accident and it is determined that you are legally over your GCWR you are opening yourself up to claim denial and litigation.

A side note on the window sticker if I may. On the left side of the sticker, is the STANDARD equipment. On an LT trim level 4x4 truck, the standard engine is the 4.3 V6. The 4.3 V6 comes only with 3.42 gears on a 4x4. So, on the left side of the sticker, it should show the 4.3 as standard, and the 3.42 gears as standard. On the right side of the sticker, is OPTIONAL equipment. The 5.3 V8 is optional equipment. The standard gear set for the 5.3 is the 3.08. If the truck is a 5.3 and has 3.42 gears, the 3.42 gears would be listed on the optional equipment side as they are optional on the 5.3, again, with the 3.08 being the standard gear choice.

So. Always either check the OPTIONAL equipment side of the window sticker, or the glovebox RPO label to verify what gears the truck really has. This really only applies to 5.3 and 6.2 1500 trucks and SUVs. HD trucks its either 4.10 gas or 3.73 diesel.

GU4 - 3.08

GU5 - 3.23

GU6 - 3.42

GT4 - 3.73

GT5 - 4.10

So...OP...I would stay away from a re-gear as you are currently leasing the truck. If you decide to upgrade, that may bite you hard when you turn it in as the truck is no longer built as it was intended/ordered. I would be eyeballing a different truck, or a lighter trailer as others have mentioned.

You can verify ratio on glovebox sticker

GU5 - 3.23

GU6 - 3.42

5.3 with NHT varies. If it is an LT trim level with NHT, its the 6L80 with 3.73 gears. If it is an LTZ trim with the 5.3 and NHT, its the 8L90 and 3.42 gears.

I was faced with a similar concern when looking for a trailer. I found a trailer that would have ticked all the boxes on my wish list and was just slightly over my weight limit. I decided I wasn't comfortable with the weight issue and decided to keep looking. Although I haven't made a purchase, I have found there are many manufacturers with excellent floor plans designed to be pulled by lighter duty vehicles. I strongly recommend you broaden your search for a more weight friendly trailer.
