Yellowstone with an older Tow Vehicle...Would you?

Granted my truck (1992) is Diesel, stick shift and 100% sensor and computer free but we drove it to Yellowstone last year with our Toy Hauler in tow from San Diego. We did 550 miles a day, passed countless "new" trucks on the side of the road with the hoods up and went thru Vegas and St. George both at 100+ degrees with the hammer down and the AC blasting.

I saw a much older Chevy square body in Yellowstone from Texas too.
