As phil said,he does well as he is in a C reefer,less competition
Night, he is also White Glove and gets the better loads. There is a lot he left out about his situation that matters.
Now for some real world comments;
I have a reefer truck (C unit) and got to tell you, don't go this route in these times.
The key is flexibility.
Having the larger truck, that carries more weight will put you in a better position to be used more often than not. Having a lift gate is better too but a reefer, unless you are independent or work for a company that allows you some flexibility of finding your own loads, don't bother - the maintenance cost will get you in the long run.
In these times, having anything less than a 20 foot box will leave you competing with vans. It happened to me when I was with FedEx and has been happening with my present company which is no fault of my present company but Fedex is a different situation.
Even if the recruiter says "you'll do fine", don't believe him and many who have been running with smaller trucks know not to say a lot.
If I was in the market, I would not hesitate to seek out a truck that is a class 8 with a 24 foot box and a lift gate. I just saw a few the other day that were under 40k but I believe that you can find them under 20k.
