A Hino 268A 26K single axle with a swap loader, I think it was the 18K lb model. Both tandems were Macks an '06 and '07. The '06 had a dual lift system and the '07 had an ampliroll 60K hook.
The dual lift was a combo cable hoist and hook lift. It worked like any "combo" not real good at either. I wouldn't suggest one.
All 3 trucks ran Allison auto's, something I would suggest.
Calculating operating costs is tough due to the nature of the business. It's hard to calculate fuel, tires and maintenance in the beginning as you won't know how many miles your trucks are going to run until you get several months for a baseline. The nature of the roll-off business is you will be everywhere across your service area.
For starters draw a service area on a map with zones. Decide the maximum distance you are willing to service and then have 1-2 zones within that max service area and price them accordingly. Closest zone is the cheapest and charge more as the zones progress.
You'll know your base truck cost to finance, insurance and tags as that doesn't change. Fuel and tires will depend on how much they roll.
Our pricing depended on many factors. The area described above but also landfill we would be going to and the gate rate they charge. The gate rates we paid were from $18 to $26 a ton. The private C&D landfills will negotiate on the gate rate depending on how much tonnage you can bring them. The more tonnage the cheaper price. The county landfills are a set rate and rarely negotiate.
For the over tonnage (above the 6 ton cap) we would add $2-5 a ton to the gate rate.
Most of the 30's we sent out had a flat rate with a 6 ton cap. $350 to 450 was the going rate depending on the many factors. However, we wouldn't truck a can across town to go to a cheaper landfill if there was a more expensive one closer. $5-6 a ton difference on a 6 ton load didn't justify 30 or more minutes of drive time. The rule of thumb was to go to the closest landfill because you can dump and return that box and be off to grab another one. The small difference in disposal costs were less than the revenue generated by keeping the truck rolling to the next can. This also plays back to service and cycle times.
We would always try and get a $50 delivery charge but you don't want to charge a GC who has several boxes that turn on a regular basis a $50 fee for every can. Also we never charged a daily can rental.
For startup capital we had around $50K cash, financed the rest through local banks and Mack financial.
