quick question and not meant to open a can of worms !!! 2019 1500 5.7 hemi 8sp 4x4 crew 5.7 box with factory Trailer brake 3:21 rear gear GVW 6900 Lbs with aftermarket I am looking at air bags added in rear coils ! I am looking at a TT 32 foot long 6283 Lbs dry with WDH as well will i be able to safely tow this trailer?
Will you be able to? That depends on your abilities as a driver. Will the truck do it? Yes but I wouldn't, that's a lot of trailer for that truck, especially considering you gave its DRY weight - once you're loaded up for a trip you're going to be looking at more weight than that, depending on what you take and what the GVW of the trailer looks like. Between the 3.21's and the length of that trailer you're likely going to have your hands full - it won't take off very well, and a trailer that long is going to catch a LOT of crosswinds and blow by, and is going to want to push you around a LOT.
As others have said, you're going to NEED a WDH with sway control. IF you add airbags (personally I wouldn't, they can mask a lot of issues), make sure you look into how to properly set up your rig with them. You won't be winning any races, so take it easy and set your speed lower, and watch out for everyone else on the road - never know when one of them is going to do something foolish.
