For me, it was SO worth it. It cost about 10 g's to put together but it holds 3 times what our one ton did. Granted, our 1 ton was smaller than yours though. On an average day, my partner and I fill this truck with chips once. Which means only one trip to the dump at the end of the day as opposed to making three runs during. Talk about saving time! Also it should be noted I've only spent about 200 bucks in fuel for both truck and chipper in the past two weeks. The 460 in our one ton would eat that in a day. I don't know much about diesels but the cummins' in our chipper and dump are easily saving me hundreds a week. They will pay for themselves in no time at all.
I just sent out an estimate for a decent sized job about 40 mins away. I'm really kicking myself for being lazy about working on the other one ton last winter... tons of pine and garbadge/rotted norway to get rid of - and there is no dump out that way for wood, so its all gotta come back to over by Turbo Kyle's house (40 mins. away).
I might just decide to do something this year like I said.. we'll see. Cash though, no loans!
Anyways, thats a big accomplishment getting that truck done.
