South Carlsbad Beach CG question?

DW and I are thinking about a stay at South Carlsbad Beach SP CG. We have a 35' 5er and F250 tow vehicle. I have looked at Google Earth and it looks a bit tight driving through, and looks like the ocean side sites are accessible on the return after the turn around. Wondered if any one has stayed there and could recommend specific sites where we might fit? We have a great back window and side window so the ocean side would be our only choice. I believe the max stay is 30 days, and I understand specific sites have some services, is that true? Any other info would be appreciated! Thanks!
