Sounds like u have a good plan now. I hauled a trailer with a mini excavator totaling about 4500lbs using a '98 Blazer. So u should be able to get 2.5 tons each trip. Class 2 hitches I think are rated at 6000lbs. I used a hand tamp on my SRW made of GeoStone. It has held up since I built a month ago. I live in North Alabama so u know it has been weather tested recently. Good luck with your project.
