Profile For J-rod

TYVM Brett...I got a call from three other companies yesterday!!! Prime, Inc; CRST Expedited and Stevens Transport, In your opinion and vast amounts of experience what are your thoughts as to which one I should attend (or) are they all the same? Do you have a ranking? LOL I know this is asking a lot but every thread I read is all about making the right choices your first year and I am my own worst critic when it come to decision making (should I do this, should I do that) LOL. thank you in advance for your expert opinion.

I am 35 years old, 6 foot 1 inches tall, and 280 pounds. DO NOT think I am a lazy person, I mostly work outside on a farm on the weekends and during the week I walk/run 5-10 miles in an effort to reduce my size. I have NO major medical problems and for all intensive purposes am a very healthy person...I just like to eat :). My concern is that I have seen/heard a lot of people saying that when they get to school there is like 80 people there and then come a day or two later there is like 25. I REALLY want this and do not want to be a statistic (unless is it a graduate). Please help me to put my mind at ease or to let me know to wait until "certain things" are done to secure my status as a CDL holder. ANY advice on this particular training program would be appreciated as well. What they do, how they do it etc. I have read other blogs on this site but most are vague..I would like specifics. Thanks in advance people!
