I'm leased to LS I used to be an indie.
Leasing give to LS is an exacting process, they hire only 2% of applicants on average. You will be required to have hazmat but won't be required to haul it , you would also be required to have tanker endorsement if you haul tanks.
The thing I like most is that I can take a month off (I'm lazy) and within a week of coming back to work I have money in the bank. I choose when, where, what I haul as there is no dispatchers. You can despite what some say make money off the board but it can be tough as there is a lot of cheap loads, I normally don't have much trouble getting good paying loads unless I end up in an area that is considered a black hole.
If you want to pull open deck do yourself a favor and buy a specialized trailer like a stretch trailer, I see loads that consistantly pay in the 7 to 8 dollar range for overlength, you can make decent money with a standard flat but the bigger money is in specialized. A word of warning when it comes to specialized, if you don't have experience you will have to work your way into it.
Now for the bad; Corporate is loaded with nazis, you will do it their way or you will be gone, they can be a real pain when it comes to safety but the upside is scales generally don't look at you as they know how tough LS is when it comes to safety.
LS also offers discounts for fuel, tires, parts, etc. To give an example, due to the recent wholesale decrease in diesel I am currently paying as much as .35 cents per gal. less than pump price, couple that with the FSC and my personal minimum rate I do pretty well....when I work
