class 7 Chevrolet Kodiak with 300hp cat and a six speed

I am currently trying to buy a truck and trailer to start hauling cars(,4 to 6) Here's my dilemma Insurance on a Class 8 truck is just too much money (dually is affordable but out of the question) I found a class 7 truck but I've read a few threads or posts that say they do not have enough power for the job at hand I will be within a 300 mile radius of Toledo ohio no major hills will this truck be a good fit for my needs also will only be part time work I have a full time job any advice will be appreciated

 

so a trip from new Boston to Columbus every sat at 650 a trip 380 miles round trip minus fixed and variable = 300 net. 1 half day after wrk running local del. pays 300 minus expenses, if I do those eight trips a month I will bring home 1800 after everything including taxes I work for the city of Toledo and Bank my overtime in to comp time which I have 18 days off as of now for the rest of the year I'm usually off three months a year, and I am planning on running more than those two trips per week so tell me how that is considered a paper route or Uber and in a year or two I can hire a full time driver

 

thank you for the insight I have looked at a few Ford's with the Cummins and they still an option the Kodiak is close to home. thank you for the reply
