I have a 2014 Tundra with a loaded Hawk.
Many say "It will work" and it KIND OF does...
But... If you offroad a lot and often, it beats the hell out of the maxed out truck.
GVWR is around 7300lbs. With the hawk and loaded to travel (and I travel light) my truck weighs in at 8800!!!
If you're generally mostly pavement, you should have no issues, other then horrible MPGs.
I've spent a ton of $ upgrading suspension, leafs, add a leafs, bags, etc..
Its at the point now, if I deflate the bags, the leafs are inverted on an old man emu lift with an add a leaf!
I've been a die hard Toyota fan my entire life and have owned nothing but for 20+ years, but the recent falling in love with my Hawk has me looking at options for sure.
I just ordered a custom set of springs from Boise Spring works and if those don't help my rear end issues, I will be taking a hard serious look at the Dodge 2500 Diesel.
Note, I never in a million years thought I would go Dodge from Toyota, but the Tundra just isn't cut out for the weight.
