Hmmmm, is this your making-a-living job, or a little side business?
The first year we had our Interstate, we met a couple near St. Mary's, GA who had a diesel Sprinter van they made special deliveries out of all over the country.
They had a futon in the back that they slept on, had over 250,000 miles on their rig and said it was just getting its' sea legs.
Needless to say, meeting them reinforced our belief that we had made the right decision.
Just wondrin', seems like it would be a great deal in lots of ways to haul for a living with your Interstate.
I see you're just a short drive from us, also in central IL. There is a great rally at Moraine View SP the second weekend in June. Would be great to see another Interstate there.
