You came here asking for opinions from people in the business, if you want to spend $15 bucks to have someone who will profit from you starving while sitting in truckstops for days and weeks on end, while his book fills your head with perfect world scenarios, which will never actually happen!
that choice is yours! Just remember he already has your money so for him "trucking" is still working for him...
Why waste our time asking our opinion of the state of trucking if you already know better?
Good Luck cause I think you are going to need a lot of it!
