I realize you need the specific vehicle to determine curb weight, which is needed to arrive with Payload numbers when comparing various TV's. Trailer Life for the 2004 model year has the 4WD 1500 Sub and 1500 Yuk (5.3/4.10) with a tow limit of 8200 and 7800. If I subtract generic curb weight numbers...
1/2 Sub - 5.3/4.10 - about 2877
1/2 Yuk - " " - about 2600
3/4 Sub - 6.0/4.10 - about 3300
Durango - 5.7/3.92 - about 3600
Sequoia - 4.7 - about 1100
Land Cruiser " " - about 1300
4Runner - " " - about 2600
Armada - 5.6/2.93 - about 1100
"" tow ""/3.36 - about 3900
Wild +/- 200lb variables, but interesting numbers. Armada tow package has to be a needle in a haystack. I'm not comfortable with 100K mile Ford/Dodge vehicles so It's really coming down to which Chevy for the family hauler.
Additional puzzle piece: 5 people plus dogs - 650lbs, 75lbs kayak or 85 canoe and we're about 1k lbs of cargo.
264BHW is 4425 dry, 510 hitch. If you go GVWR 6500 * 12% = 780 hitch
The Equalizer add 100lbs. I'm going to need 2K lbs for cargo min?
If the tow package is so important why do they not get their own column numbers on Trailer Life like the Armada did? Perhaps oil/trans cooler are only longevity factors. I'll do some gas MPG comparison for motor types to see if the 5.3/4.10 is my magic combo or not.
P.S. My little Explorer has zero tail wag with cross winds/semi's or pot hole swerving. Guess the EQ12K does the squeaky job. Maybe I don't need the Sub wheel base.
