Hi Beth,
They are all very capable tow vehicles - despite those on here who believe that one can & should only tow with a big ole truck/suv .... but there's more to it on the details of the ones to which you're drawn.
First - you'll need to base your TV rating not on the dry/empty weight - but on the trailers' actual wet & loaded gross wt. - & the hitch wt. may also be a limiting factor. So look at the factory towing, hitch & combined vehicle/rig ratings for any tow vehicle (TV) which you consider.
As for trailers - you may also want to look at some of the Vintage Kin "Silver Twinkie" trailers out there too - such as Avion, Silver Streak, Curtis Wright, etc. - which are all as well or better built than the vintage ASs (I know that's heresy to some on here, but it's the facts), & will be more unique when you go to vintage trailer rallies, etc. Note that my wife & I are Avion owners, for full disclosure!
I see that you're in mountainous CO, so I agree wityh your V8 leaning - & if you're going to do much mountain road/freeway towing, then you may want to get either a V8 or diesel powered TV, vs. the gas V6 - even if they are rated to tow your eventual trailer. Note that
the V8s will usually get the same or better mpg when towing as the V6s - since the more powerful V8 is working less hard, than the smaller & less powerful V6s. The V6s only have an mpg edge when unhitched, & then it's often only 1-2+/- mpg more - so the benefit isn't much in many cases.
FYI - We had rented several new 2013 4.0L V6 Nissan Pathfinders back in 2013 for our TV with our 3500+/- lb. wet & loaded
1960 Avion T20 (20'-6" L.) - & found that they were constantly revving high & droning on even modest grades (US-101/PCH Camarillo to Thousand Oaks) - which would drive us nuts on a longer hilly/mountainous trip!
When you consider the Touareg - also include the Audi Q7 & Porsche Cayenne cousins in the VW/Audi/Porsche Group (V/A/P), since they're all about the same pricing range in the used market - & are often less than Toyota/Lexus comparables - usually with more miles & harder use. However, try to stick with the later series ones in 2007/08> in order to avoid earlier issues (I'm most familiar with the Cayennes & those are best `08> & had no `07).
They are mostly all of the V/A/P trio in any motor choice rated to tow 7000-7700+/- lbs. with 700 lb hitch wt. - with Hybrids down-rated a tad to +/- 6000 lbs/600 lbs., as are the slightly longer 3-row Q7, due to a bit more basic vehicle weight. So all will work for most of what you're looking for in trailers' gross weights. Also note that their 3.0-3.6L gasoline V6s are only about +/-2 mpg better than the comparable V8 versions, as noted above (excluding Turbos) - so you're not giving away much.
You can glean a lot more info on the V/A/P trio & other mid-sized SUVs at this link on here:

My V/A/P & BMW, MBZ, Toyota/Lexus & Honda etc. Factory Tech trained mechanic of 41+ years steered me away from the BMW X5 & Nissan/Infinity SUVs for quality & reliability reasons (also Consumer Reports says same), but likes Toyota/Lexus & VW/Audi/Porsche SUVs - & he also likes Honda/Acura (but we want a V8 & they only have V6).
He also thinks that the VW/Audi/Porsche Diesel V6 is a great machine & all his owners love them (as do owners on here & my PCA buddies with them) - but he said it's best to avoid them, even when the legal settlement is approved with Cal/CARB & EPA smog fixes, because whatever the approved emissions fix is - it won't run like it did originally, & because VW Group is washing their hands of diesels in the USA/Canada, so the parts & support will eventually just go away (he knows the I keep our vehicles long term). This caution only applies to the VW sourced 3.0L diesel V6 - not other makes.
So there may be some great deals on new V/A/P diesels sold at big discounts as used once the issue is approved - as well as used ones, but it may not be such a great deal once the factory warranty is over.
We're likewise looking for a mid-sized V8 powered SUV for the above reasons & due to our narrow streets & driveway with tight maneuvering quarters as well as because my wife won't drive a big pick-up/SUV, & are focused on an `08-14 Cayenne S with the normally aspirated V8.
We also looked at the 4Runner & GZ470/460 & drove a couple, & we didn't like the tall/narrow stance coupled with compliant off-road-intended suspension for resisting sway & side-forces/winds/18 wheelers, not to mention seats in the GX which were hard as a park bench & uncomfortable on a short 15 min. test drive. We also HATE the "Gaping Maw" styling of the newer Lexus cars - just plain ugly! Of course - those are all more personal taste, so if you feel differently, then you cannot beat the known long term reliability of Toyota/Lexus.
However - YES they do have a hitch receiver conflict on the GX (& 4Runner) with the Hensley Cub stinger I use (took it with me to test drive), which would force me to take out the spare & carry it in the rear cargo area. Not a good design, & even if your tow bar/hitch bar/stinger will fit butted up against the spare tire - would you really want to trust a WD hitch to just +/- 3" of receiver!!??
This topic at the link below was also posted on here a few days before we test drove a really nice GX, & while much of the cause was driver error, I was concerned about the high center of gravity & sway of the GX when I did "practice evasive maneuvers" in a parking lot during our GX test drive.

I'd suggest you & your other potential drivers &/or an objective friend go out & test drive some of your top candidates, in order to find which ones suit you best, then you can look for only specific ones of those which you like whenever you're ready to buy.
As for the interim, you can rent a Ford F250 from Enterprise Commercial - or if a local Toyota/Lexus dealer has any properly tow equipped SUVs/Pick-ups in their TRAC rental fleet (most only have cars for when yours is in service - so you'll have to call around) - near you to tow your trailer home, if you have it before your TV (as we've done since July 2012). If you get the TV first, then you just need to size the trailer for the towing specs of the TV. So no need to rush the decision for either trailer or TV.
Hopefully this was helpful to your decision process.
Cheers!
Tom
