3/4 or 1 ton SUV ?

Three years ago we pulled a 5x8 enclosed trailer with our 9 passenger 2012 GMC Savana explorer van, 3 adults and 4 kids and cargo trailer usually at about 3k lbs. We had brake rotors replaced every 3 trips or so, whenever the braking vibration would get unbearable. The 6.0 motor was good enough for this but would not be enough for a TT in tow, and I could not imagine what the wind blowing it around would feel like as that was pretty unbearable at times as well.. When the A/C in the van started blowing warm was the final straw and we will never go back to a motor crammed into a compartment again (that includes bus/Class A). Be smart and buy a tow vehicle with a real hood and built stout enough for pulling AND braking. The '05 Excursion is the last real option for passenger hauling +trailer, if you can get over the late 90's interior and features for what people selling them wish they were worth. Maybe, thanks to coronavirus and the resurrection of road travel mixed with the collapse of the cruise industry, we may finally see the return of the true HD diesel powered 3/4t and 1ton SUV, not the thing Nissan has right now that is a towing joke. I imagine if Ford (for example) makes a long wheel base 2022 Excursion-Max with 7.4L gas, they wouldn't be able to build them fast enough for all of the RV's out there being piddled along with terrible tow vehicles.

EDIT: I forgot to add that we bought a 26' 6200# (loaded) TT and pulled it a couple times with our 2017 Infiniti QX80 4x4. Its 5.6 motor did surprisingly well, better than the 6.0 van, but could also be the better transmission with it. But the rear end was too squishy unfortunately and was so obviously overloaded at the tongue with the equalizer 4-point sway WDH, anything off interstate was like gambling whether staying at speed limit was possible (due to rear end dipping and rocking at higher speeds). It's been traded for a choppy ridin' dually truck that won't break under pressure.
