I would have to call bigben on that 15 min deal. I love when guys start a pissing contest but did not drink water beforehand....lol
I would also bet his cost per hour is drastically higher than the guy doing the job.
You also have equal travel time on a small job like that as well....most cranes charge port to port and if you own you costs are continuous as well.
Not sure why he is busting your balls...I am sure you made money on the job.
He could bring his 70 ton crane around here and run up one hell of a fuel bill getting to all the jobs. There is little need for a crane in rural america. I am sure they are nice but we rent when we need one and we rent what we need.
