Yeah, please check that if you can; I think I'm OK but it never hurts to check. I thought if I'm earth grounding on both ends it was OK to tie grounds and neutrals to the same bus bar. On the grounding rod, as much as I'd like to ditch it horizontally, the local code here says the ground rod has to be driven in vertically to get down to moisture for better conduction. Something else to check on. Not meeting code means not getting reimbursed by insurance companies!
Thanks,
Mike
