in Wisconsin there is/was a org. that ran 3.0 and 2.6 at the same time, not changing the sled. there was a significant difference in distances. they never asked the 3.0 guys to give up weight. although there was only one competitive truck that ran with them. some tracks this year a few times one or 2 2.6 trucks walked out with the w.. but like I said there was only one competitive 3.0 truck.. the difference in distance I'd have to guess 1000lbs would be significant. although we have plenty of fundraiser pulls, brush hooks, or firemans picnics that have a open class or unlimited diesel class. where enough of the trucks from surrounding orgs show up to hook. and we could try to do weight changes to level the field... seeing how once july roles around I've got atleast 3-5 pulls a week to choose from within a 2 hour driving radius.
