Wow guys! This is 100% personal use! I am a partner in a CPA firm so no question about this ever being for work.
Also I am in Oregon, my truck is already 'T' Plated and licensed for 26,000 and under because I own a couple other trailers rated over 8,000 pounds already. (14k dump trailer and 10K Enclosed Trailer) Here in Oregon T plates are required for 8k trailers or more. Does not matter if personal or business for the T plates. $764 a year to be rated at 26k for the truck. Trailers over 8K have Perm plates and are included in the truck license.
I want to do 12k cause its not much more then a 10K and just gives me a little more room. Who knows what I might end up with on the trailer; Tractors, diesel pickups, Suburbans, loaded with 4 or 5 quads, wood etc...it would be of coarse 100% personal use. Never for making money. As long as they don't add to the commerce definition, adding value to one's home
The reason for not doing 14k is my 2011 truck has a GVW just over 12K. So a 14k trailer plus a slightly over 12k truck could put me into some 26K CDL issues in differnt states. Yes it would still all be 100% personal, but I don't want to be stuck on weigh stations argueing with LEO's while on vacation.
And generally out of Oregon travel we would have our Truck Camper on the truck and toys on the trailer. So most of the time we'd be looking like an RV'r.
One thing I did learn about some of the Diamond C trailers is when they call it a 12k trailer it may have 5,200 axles...which I don't like. To me a 10k trailer has 5,200 axles, a 14k trailer has 7k axles, and a 12k trailer should have 6k axles, etc...
