W/O the GRCS it would be unlikely that I'd have as much rigging as I do, but if I did I could have done it with the truck on that particular job.
The option that was suppose to be going down that morning was bringing in a crane, I'd imagine the 100 ton which brings a 6 hour $230 (plus 15%) charge. They would have had to cut several limbs off surrounding trees to have enough room to work, and getting the tree untangled might have been a bit of time.
Over all with a crane it would have probably taken me roughly the same time, but at a much higher cost.
Without the crane the job would probably have taken an extra thirty minutes with a truck, perhaps a bit more. Most jobs wouldn't have had enough room to work like that with a truck though.
