The TV/TT combo has already been hashed out. The Tahoe should be well under GVWR even with about 1400 pounds of payload per the Tire and Loading sticker. A good WDH with integrated sway control is important for any TT.
I love my Reese Strait Line, but I the Equalizer for $450 is a great value and what I recommend.

Thanks everyone for your input. After talking to the hitch place near me, I decided against the Hensley. They would be the ones I'd have work on it and they are not as familiar with it as the Reese dual cam. So, I think I've settled on that, but it was a close race with the Equalizer. He also mentioned that if I have an issue with the Hensley on the road, fewer places will know how to service it properly cause they aren't as familiar with them. That is a big selling point for me. I'm not enough of a gearhead at the moment to even try to play around with a $2500 piece of equipment.
I'm a little overwhelmed with learning about the trailer/towing and all that for the moment, so the thought of learning how to install the Hensley just didn't appeal to me. Maybe down the road.
As far as how to avoid having the dealer install it, they said they install the parts on the truck before we pick it up and because we aren't traveling far we'd drive the trailer to them without sway control and then they'd install the rest.
Once I buy I'll report back on how everything worked out. Now to try and get the price of the trailer negotiated...
You are doing the right thing, asking the right questions. Making this planning the hard part now will make the actual experience (towing, and RVing) much more enjoyable with your family.
