[s-cars] Non Audi, but VAG question.... VW Touareg V10 TDI vs. V8 opinions?

[Jim Fleischer]

Hey all,

Sorry for the non-Audi topic, but this list is what I feel to be the best knowledge base of most things automotive, so hence my reaching out to you for this topic.
I’m looking for a tow vehicle to tow a 23’-25’ Airstream (Sub 4,000 lb. Dry weight) throughout the western US, and mostly throughout the Rocky Mountains on a regular basis as I travel for business and avoid hotels/AirBnB etc.  I’d like to stay away from the typical Ford/Chevy/Dodge pickups, have been looking at some Toyota Tundra/Land Cruiser options and some others, but have always been an Audi fan and have a soft spot for the Touareg V10 TDI since it came out in 2004.  I know the V10’s are few and far between but they are out there, but I come across so many more V8’s for much less money that they are a perceived option at the moment.  Tow capacity is listed as the same.  Wondering about things like drivetrain durability, air suspension and such.  As a long time Audi owner, I feel I can deal with the small stuff like switches, etc. and am familiar with the large oil capacity of the TDI and the expense that comes with it.  Gas mileage is a plus with the V10 over the V8, but the difference in initial cost to buy would cancel that out I’m assuming.  I’m looking at MY 2004-2007’s for pretty much everything.

So, any thoughts and BTDT opinion from the List?  I have done a fair amount of research on the Airstream and Travel Trailer forums and have ruled out my first couple of options due to what I found there (Land Rover Discovery 2 and Range Rover) and have come back to VAG as expected.  Thanks for the info, and feel free to email me directly if this post is not of interest to the masses.  

Best regards,
