Diesel fuel is about $1.37 per litre here, $5 US gallon. Petrol (gasoline) $1.20,
about $4.50 US.
What we average is Chip truck $50 per day, Chipper $50 per day, bucket truck $50 per day, small truck $30 per day, two stroke and stump machine $20 per day. Total average $200 per day, $1k per week. This can vary greatly, but is average for us over a year.
With the maintenance costs, I allow for saw parts, chipper blades etc as well as vehicle maint.
Miscellaneous can include permits and licencing, some repairs to damage, the odd fence or damaged turf, work clothing and a lot of things you don't readily think of.
I hope I'm not too far off the track.
Cheers.
