That is how I read the man page, too, long ago. But when I tried the -o option on the commandline, I was unable to send mount all of the mount_nfs commandline switches I needed. I either misunderstand the mount -o option, or it doesn't work for all of the mount_nfs stuff I tried to send it.
In other words, the -o option seems to not like any of the many switches understood by mount_nfs .... hence I seemed to be forced to use mount_nfs directly. And that precludes using it in fstab.
You are not restricted to only the -o option with fstab. The native mount_nfs switches work fine with it. This is stated in the second half of the last sentence I quoted above (note the "and"). Thus, the same options you use on the command line work with fstab.

I don't know. Since mount wasn't able to understand those switches on the commandline, I never tried anything in fstab, for the sake of not causing any problems with my boot.
The handbook page on nfs has a few simple examples toward the bottom (first hit on a Google search for "freebsd nfs fstab"):
http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/network-nfs.html
To test the line I gave you just add it to /etc/fstab and see if "mount /dellbak" works. It'll give you an error message if something is wrong. For example, the options specified work perfectly for me and the mount command completes successfully. Adding a "-z" to it gives an illegal option error.
# grep shared /etc/fstab
server:/shared /mnt nfs rw,-s,-x=2,-T 0 0
# mount /mnt
# umount /mnt
<add "-z">
# grep shared /etc/fstab
server:/shared /mnt nfs rw,-s,-x=2,-T,-z 0 0
# mount /mnt
mount_nfs: illegal option -- z
usage: mount_nfs [-23bcdiLlNPsTU] [-a maxreadahead] [-D deadthresh]

rhost:path nodeAnyone tried that sort of stuff in fstab? I'm a little skeptical.
I use "that sort of stuff" and have for a long time. Here's one of my fstab lines:
optimator:/usr/home /usr/home nfs rw,-3,-T,-r=32768,-w=32768 0 0
It's obvious you don't believe me but why are you unwilling to try it yourself?
