Been in a few including 150's silverado 1500, and a Denali 2500 a few times which is the flash silverado.
They arent sh1+ To drive
There furnished like your lounge room probably better
They have every conceivable option including prewire (with a plug) for a teshonka brake controller
They don't feel big until you try and park them
They tow like you won't belive (power and stability)
The 6.6 Duramax has diesel grunt like you won't belive existed (this from a 200 driver)
The fuel consumption in both the 5 or 6 litre petrol and the 6.6 Duramax will impress you.
And there darn well built and about usd$55k to buy.
But there a nightmare here in the carparks and shopping centres (which is a plus to me)
And could see too many getting through the high country tracks
