I have heard these terms before and can pretty much figure out what Flatbed and Dry Van is but what about reefer? I have no idea what this entails? Which one would get the most pay? I figure flatbed would be the hardest.
Unless you're a masochist I'd stay away from reefer. Otherwise you'll be learning all kinds of new and exciting words like, meat patch, grocery warehouse, and lumpers oh my! But seriously. Reefer loads always had to be delivered yesterday! Go to sleep for a few hours and you'll wake up to a beeping Qualcomm with message after message asking "why aren't you rollin'!" I wouldn't recommend it.
I would,I have been running Reefer for 13 years and its not as bad as most people think. I'm not saying its all cookies and milk,becouse it does have its dissadvantages but there are also some advantages. Most of what I haul is food,It sure helps on the weekly grocery bill when you have the freshest fruits and vegies to pick from.
Flatbed easily pays the best coming out of 90% of the areas in the USA depending on seasonality. But like you said, it is the hardest and you need to be willing to do the work (or if you own the company find a driver willing to do the work).
I think they are referring to tarping loads. Some tarps can weight near 100lbs and mix that with the beating sun, freezing wind, or just plain gusts of wind, and you have a job in itself.
