If you are only hauling your own stuff, you don't need a commercial license.
If the truck weighs less than 26,000, you don't need anything other than your Class C
If the truck weighs more than 26,000, you need a Non Commercial Class B
If you add a trailer that's 10K and the combined rig weighs more than 26K, you need a class A (noncommercial)
If the truck weighs less than 26,000, the trailer weighs more than 10,000, and as long as the combined rig weighs less than 26,000, a Class C is fine ... BUT ... if pulling a trailer that is more than 10,00 lbs, you still need a DOT Medical, even with a Class C license.
Simply put -- No matter what the truck is, ANY trailer more than 10,000 lbs requires a DOT medical.
10K is pretty easy to get to with a load like that ... better check your weight some time. If you get spot checked by DOT, they can put your rig out of service on the spot, meaning you aren't allowed to drive it anymore until you have the needed credentials (but you can call someone else to come get it). BOLO for all black Tahoes with tinted windows and spotlights ... Don't ask how I know this ...
As far as I know, if you are managing your diabetes, you can still get a medical, but it may only be for a year or less, depending on what your examiner determines.
Sure, they don't mess with pickup rigs like yours .. much. Just don't be out on the road when the DOT man is having a slow day ...
