I agree, Justin. No way in Hell would I pay $30K for a 20 year old truck.
And I also agree with your assessment that a forestry truck is the best choice for your current situation. You only have one driver, yourself. Your uncle probably won't be working with you more than another year or so and a rear mount bucket means you need a driver for the chip truck. An employee you don't have yet.
I wonder if it could catch a ride on a heavy-hauler. If it's on a low-boy, and the low-boy breaks down, it's someone else's wallet that's going to be hurting.
Here's a 2005, 75' WH, has an elevator, 210 hp dt466, runs and drives super, great condition, Terex, upper/lower over center, smooth and quick. 95k maybe a deal possible. I was the last to use this truck, very well maintained.
