I’d say, depends on State or region. For Phoenix, flat is better. Lots of steel, lumber, construction loads. My advice, drive around your area, what do you see? Stop in a local truck stop and ask a local flatbeddder. Don’t assume.
I basically taught myself flatbedding. I always looked at other driver's securement methods and tweaked them to my satisfaction. I always over did it, and it has saved me a couple times.
I don't recall paper rolls being hauled on a flatbed. I don't think any tarp is totally water tight, although, I'm sure it's been done. I hauled plenty of rolls of paper in a van, until the paper industry went kaput in the Badger, and never had a problem
USG will load paper loads shotgun on a flat. Looks like heavy manila paper, set in a customer provided bunk or cradle.
New development. Now I'm looking for a new carrier. I had my first preventable accident in 4 years. Leaned over to adjust climate control and pulled the wheel with me. Stupid rookie move. Ran in a ditch an took put a sign. Trucks getting fixed, i could have driven it to the shop, but was in the middle of nowhere, so I had them tow it. So now I think I'm screwed. Boss said his insurance dropped me, as he is a small carrier. ATS said I have to wait 12 months with no preventable accidents. Anyone have an idea of who I should look at?
That's what I was told. 3 accidents in 4 years. 1 hit and run 4 years ago that shattered my hand. No fault. Non preventable Another 4 months ago. Car came across the median and into my side (tried to take same exit at last second) No fault, non preventable Whatever his reason, it's his company.
So it’s not 1 accident in 4 years, it’s 3. Preventable or not, the insurance company looks at you as a severe liability. Chances are, every other insurance company will look at you in the same way.
