My truck is a crew cab (4dr) with short box
The thing with crew cab is you can go over axle ratings fast. But depends on the truck...
Example:::
Your axles are 3900 lbs each from door tag
Full tank of fuel, passengers, gear. Your weight at scales says 3200 lbs...
That means 700 lbs left for tongue weight... Hummmm 800 plus lb TW of trailer your looking at...
May be over axles and I never advise that ever!!!!
Although the WD hitch may move some off its often not enough when borderline...
My advice before you buy anything...
Fill tank, put 4 people in truck, and some gear. Get weighed at a cat scale. two axle weights. Then take the axle weights on your door tag and subtract from your scale weights...
That will tell you what you can and should tow...
Also post your tire max psi and weight ratings...
And also post your hitch ratings with WD...( should be a tag)
