How "new" is your truck - how many miles? I wouldn't tow anything that heavy or that far in the first couple thousand miles.
Also, do the V6s come with a transmission cooler like the Duramaxes? I don't think so, but I'm not positive, I haven't paid much attention to the V6. If not, I'd definitely add one before towing in the desert.
I might be concerned about the trailer as well....are you buying this from someone you know/trust? Do the brakes work? How old are the tires? Does it have a spare? Lots of potential issues here that are worth looking into before you make the trip.
