And, the sub contractors - the ones doing the work (immigrants) - they had a wide variety of vehicles. I took note that some had Camrys, Prius, old Golfs, small picks ups like Rangers, and some older mid size trucks that were visually heavily used. Else, they used commercial trucks or vans. When did I see the prestigious full cab F150s or Silverado RTs? When I originally interviewed GCs which is when I noticed they drove their clean and new trucks.
If the road existed in the 1990s, it's quite likely accessible by a mid-size SUV. Similarly, if families of 4 could go camping with cars from 1950-2000, you can today as well. In fact, you can get more compact tents, etc. today.
Trucks and huge SUVs come in handy if you want to bring lots of modern toys like gigantic prestige coolers and 4x4s.
Vehicles these days are shockingly capable.
