CT got rid of the Non-Commercial A&B. So GVWR 26K or trailer 10k (not RV) or 15k RV, so at or above the marks, you need a CDL. With the recent "Upgrades" at CT DMV, (the results have made the national news), less info is available on-line, and trying to get hold of a live person via phone is nearly impossible. It's the odd day when the lines aren't outside the building.
The non-RV trailer is a national issue, so bad that manufacturers are marking some models 9990#.
I was thinking of upgrading to a larger 5er or TH to full time if the company wants to send me on a 18-24+ month away job. Although, it might be worth it to change residency (depending on state) and relicense there.
