You didn't mention whether it could be considered Commercial use or not? Be very certain you never exceed 10,000lbs on on trailer, I don't remember if the break point on the trailer is 10,000, or 10,0001 lbs you make want to find out and reregister trailer and minor cost if that applies( you do not get to deduct tongue weight). You also did not mentioned whether its diesel ( fuel permits on interstate travel , usually when exceeding 26,000lbs) trip permits, etc. If you seldom leave the state, the better. Don't haul any hazard materials you don't have to ( race car fuel tank is OK) I am not an expert, I've just been tripped up a number of times. "safe" is hard to answer, but it does sound right.
You keep referring to registering your trailer. I'm in Mich here and for a private trailer(non-commercial) we have a permanent plate and I haul it with my pick up with a normal pick up plate. Also I was told by Chrylers Hasmat group we could haul less than 110 gals of fuel otherwise I had to have a CDL. So from what your saying I have no idea if I'm legal or not
