Good points. The extra detail there helps.
I haven't been stopped with my trailer (registered in my home state), but they're now cracking down on inspections and such which have gone unenforced until recently. That's one of my issues for wanting to move registration out of state. my 24' enclosed costs something like $40/yr to inspect and over $100/yr to register in TX--- that's twice what my car costs! At least insurance is cheap on it in relation to my car...

We've also run into those issues at work regarding the CDL. It was in a New england area state where a couple coworkers got stopped in our 1 ton van pulling a small single-axle trailer, and slapped with a whoooole bunch of fines because they were pulling company property through their state (across state lines) without a CDL and logbook and etc on the van.

So instead of renting trucks/trailers and driving ourselves, we're now relegated to paying 3x the price for a hot shot or LTL shipment to carry a 1200lb part a couple hundred miles.
