Since you alluded to a fullsize van, I'm going to assume that 4x4 is not a priority for you, which frees you up when it comes to tow vehicle set up.
I am personally going to recommend, for your consideration three vehicles
1) Suburban 2500 with an 8.1 big block (03-07 ish)
2) Excursion V10 (this vehicle will be the easiest to find)
3) 12 Passenger E350 with a V10
There are many half tons that on paper would handle this rig... A F150 with max tow or an Expedition with Max Trailering, GM truck with NHT trailering package would do great.
Your TV will need enough payload to carry you, your family, and your trailer tongue weight.
As to Weight distribution the Hensley/ProPride twins and the PullRite hitches are the best, and the most expensive (for a reason).
The next best are the hitches that actively work to prevent sway and I have only found two hitches in the sub $1000.00 mark that fit this description. These are the BlueOx Sway Pro and the Reese Straightline HP dual cam system.
Next are the integrated friction sway control hitches... These are the E2, Equal-i-zer, and a few others I can't remember right now.
Finally, you have standard WD hitches from Reese, ProSeries, Curt, Eaz-Lift, and several generic versions (harbor freight...etc)... These hitches do a great job providing weight distribution but need add on friction sway bars for sway control. For your size trailer you would need two of them.
All of these hitches come in many different weight ratings... I'd suggest going up to the closest bar size to your Tongue weight. I really doubt you will have 600 lbs tongue weight loaded... More like 8-900 lbs... So instead of 800 lb bars you will need 1000 lb bars.
There are a lot of choices, I choose the standard WD hitch and two friction bars... My rig handled great and was rock solid behind my HD truck.
Thanks!
