I think Chris answered your questions except if you need details on the equipment, the dump has a 16' box that we plan to adapt the gate to a swing gate (makes it easier to load). The excavator is a John Deere 60D long arm. Good luck with your purchase an as Chris said looking back we have no regrets going this way. Our first attempt was with a JD-CT332 tracked skid steer but it made more mess and was limited to augured footings and 10' depth. Since we switched to the excavator we have very little site clean up. Out of the ground and straight into the truck. Also with the larger truck we able to haul most jobs off in one trip and bring the equipment back without over loading the truck. I hope we have helped with your planning.
