There's a couple of threads on here already about this. Folks have strong opinions. The chart #16plati posted is really all you need to know...the rest is just opinions.
And here's mine......
I don't tow anything so I didn't get it. I was already spending $80k and didn't see the need to spend an additional $1500 for something I did not need. Folks on here will tell you "but you did need it even if you aren't towing...for the upgraded radiator and a locking rear diff and the faster 0-60 time and the higher resale value and yada yada yada." But here's the thing: no, I don't.
I don't need an upgraded radiator because I'm not towing and the "regular" radiator is just fine in all other cases.
I'm not rock crawling with this thing and the "regular" 4wd is just fine for the light off-roading I need to do to get to campsites.
I'm not racing anyone, so I don't need a faster 0-60 time. 400 hp is just fine thankyouverymuch. The thing is damn sprightly with the 3.31 and I'm happy to have the marginally better highway gas mileage.
The higher resale value is arguable, but if I invest my $1500 I'll make more than I would have in resale.
I'm not pulling the thing behind an RV, so I don't care if it can be towed flat or not...if it breaks down, that's the towing company's problem.
The package is called a towing package for a reason. Sure there are other benefits, but it's not called a "performance package". It's for towing.
So again, 16Plati's chart is where you really should start and stop your analysis. If something on there makes you want to spend $1500, go for it. If it doesn't, don't.
