This is really a few questions in one. This is a 26' enclosed trailer.

1) Where should the car be positioned in the trailer? Should it be centered over the trailer wheels or further forward/back? I know this depends on how you want the weight in the trailer distributed, but, in general, what's the best position?

2) Now that I have the car position, where do I put the d-rings? This probably depends on what I use on the car as an attachment point, so what should I use for that?

3) How do I mount the d-ring? I've been looking at the recessed ones and they require a hole be cut in the floor. Is it easiest to do this with a reciprocating saw or something else?

Thanks for any info. I'd like to get this right the first time.
