100 times easier. You can get a nice suburban like this for around 4K

Crew cab silverados are harder to come by in that generation and you would pay 6-8K for a similarly equipped Silverado extended cab vs the Burb.
Plus I have been wanting to build a unique rig and try to get it featured in a magazine of some kind. Just a personal goal of mine.
I like the camper trailer as its setup now, the Cherokee pulls it and all is good but it leaves a lot to be desired when exploring. Turning it around in the back country is a chore and setting the camper on a rig like that would up its exploring capability a ton. Plus being able to setup at events like the Hill Climb with ease.
Lots of positives to this setup in my opinion, like LS swap ability down the road. Tons of LQ9 6.0L's on the internet to be had. The right cam, tune and intake/exhaust and it would be a beast.
