I'm new to the forum and not yet in expediting. I do have B CDL w/HZ and was thinking about buying a D unit. All the companies I have looked at require a sleeper on your unit. The cost for a good used sleeper unit seems to be around 50k, were as I can find low cost non-sleeper units under 20k. Is there any companies that don't require one. There's alot of good info on this site and I thank everyone here for the info I have found.
