I'm not exactly sure of your situation, but I've got a 18' car hauler (12k capacity) that is just north of SLC in Utah. I see you are in cali, and Im sure thats farther than you want to drive to get a trailer.
As far as hooking it up, (and not to undermind any other posts) you DO NOT, for any reason wrap the chains or straps around the axle housing, NEVER. You always 100% of the time secure the straps/chains to the chassis. The point needs to be in a place that will not give. and you want to compress the suspension of the vehicle, that is what the suspension on the trailer is for.
I also usually will pull my truck on the trailer, and secure the rear straps, put the truck back in drive (4lo) and compress the suspension and then secure the front, and tighten it down as much as I can, take out of park and let the truck settle and put it back in park. If I REALLY wanted to, I could always use the winch.
In the pic link below, it looks like the rear straps may be going to the rea axle, they aren't. Its going to the rear crossmember just above the rear axle and is connected at the point where the crossmemeber meets the frame, the front is connected to the bumper.
