Diamondpilot, what do you normally haul? Rolling equipment? I only ask as I find the fenders always in the way with low boys but I'm usually side loading equipment or pallets. Even just loading hay you lose a lot of capacity with narrow low boys. Also, what was your problem with the dual tandems? Most people really like them after a tridem singles. I've been tempted to look at tandem singles with 17.5's if I ever replaced my axles. I've seen a few around town that seem stout with solid disc wheels.
I just dont care for Dually trucks and I guess it carries over to trailers. I had a Dually GMC in the late 90's and it was the second worst vehicle in mud and snow I have ever driven. First being my F-150 Lightning but it was never really meant for that stuff. Yes, the Dually GMC was a 4x4 and it had a Boss V Plow on it.
My issue with my dually trailer was maintenance issues. Tough to work on. Finding tires on a Saturday when a blow out occurs in the middle of no where, ect. Heck, with my tri axle 18,000# trailer I once made it home 400 miles on a Sunday running 3 car tires after a rash of brand new Carlisle's loosing the tread just north of Knoxville TN. Try doing that with 17.5" wheels on a Sunday.
What do I haul??? Here is what has been on it in the last 3 weeks or so. A 40 HP tractor with FEL, a Chevy Cobalt (broken timing belt), a Chrysler PT Cruiser (broken timing belt), a ZTR, 5 Round Bales, 3 Pallets of Mulch in bags, 4 Rick's of Fire Wood, Furniture, a College Kids Dorm Stuff, Lumber, A City Truck Snow Plow 12'x4' monster, and probably a few other items.
The two cars with broken timing belts were for a friend who buys them off CL with issues and flips them.
