Truck setup for flatbed but...

hello I just bought My first truck
2004 freightliner columbia 120 with a detroit 60 14l 10 gears and 3.58 rear 230 wheelbase it has 1102836 the motor was rebuilt in 2015. I paid $7500.

The truck is setup for flatbed. It has a headache rack with all the chains etc. a generator box and extra toolbox mounted on the side.

The thingis I want to try my hand at containers first. Would I still be able to haul containers with the headache rack on the back.
Thanks for feedback. This maybe a stupid question....

 

I only have food service experience as a company driver. And I never went to school. Always been local. SO, I figure I will learn the different segments as I go and see what I like. I will make money bc I got low overhead.

 

Update things have been up and down. After the first week I had to replace the radiator and some CAC conponents. $4000 It took about 2 weeks bc they had to order the parts. That was over a month ago since then everything has ran smoothly. I ended up hiring a driver and I am still working for a company since I make north of 130k. I plan on buying 2 more trucks and getting my authority by March 2018. I have driver lined up already. I have a direct customer that is just waiting on me. Im really excited about the up and coming year. Im sure it will be ups and downs and thats ok with us.
My plan is pretty solid. What are somethings that I should be preparing for? Im going to start another post focusing on my journey.
