This is a popular question and the answer is...nope there is no one answer.
If I had it to do again, I would go with a 3/4 ton (2500) series diesel for the TV just because of the torgue and extra weight capacity. I have a 8500# Windjammer with about 1,100# actual hitch weight loaded and am using the Equalizer 1400# hitch with no issue. BTW, I pull mine with a 2013 Sierra 1500, 5.3L and don't have but one issue...I will have to trade up to a heavier TV before I can get the 40' 5th wheel my wife wants next.
There are as many WDH on the market as there are RV's I think. We were given a 1000# Trekker at delivery and found later that it was not heavy enough to level the TV. The dealer refunded the money as I had bought another one. Just make sure it has built-in sway control (easier to use than working with a separate sway controller) and is heavy enough for the hitch weight. Do NOT go by the factory specs for hitch weight as that is empty of all fluids, does not take into account if a extra accessory package with an additional AC unit has been added, or your camping stuff. My specs said hitch weight was 860#
With an 8000# trailer, at least do a 1200# hitch.
