I am considering downsizing in the future from a tractor/low-boy trailer to a 3500-5500 size truck and a 10 ton 5th wheel trailer. I'm getting my a$$ kicked on insurance, plates, and especially fuel costs and tire wear. For you guys who are running the set-up that I'm considering, what are you paying for insurance and plates? Also, what kind of fuel milage to you get when pulling a heavy load? I know there are many variables when it comes to these, I'm just trying to get some ballpark numbers. Has anyone else switched from my current set-up to the other? The only negative for me would be that I could only haul one machine at a time, but I think I could save money in the end and have a newer rig. It just feels like I'm constantly buying tires and burning more fuel than I need to.
