I vote for using a diesel also. I am a believer in using those for long range trips like you are planning.
Diesel have a few advantages,like being fuel injected,get slightly better mpg,but a few disadvantages are diesel fuel isn't always as easily found in some places,so you'd better have dual tanks or carry extra--also in colder climates they can be harder to get started,and require 2 batteries..it would suck if you run low on fuel and the fuel lines got airbound on a steep grade,you'd probably kill the batteries trying to get it primed again..

Fuel consumption like that is nuts, it would definitely limit the trip range if we were getting further from civilization.
Yeppers. Watching Dave refill his 30-gallon tank 5 or 6 times when I refilled my 20-gallon tank twice...I'm sold on the setup that I have. And I drove to the meetup point, he trailered.Fuel consumption like that is nuts, it would definitely limit the trip range if we were getting further from civilization.
When selecting a Suburban, I looked far and wide for a diesel rig because that was one of my top requirements for long-haul trips. I don't have a problem waiting for it to wind up to road speed, having to stop every day for gas did not give me big block envy.

Use that 6.5 with topper and roof top tent.
Nice swing away bumper in back.. windows that open on the sides of topper. Pass through window to topper.
And most importantly it looks like that truck has matching wheels...![]()

I met these people (Ron and Viv) in Sedona, AZ. They were heading to the arctic. Looks like they made it.
