Anyone know if installing a GFI on the load side of another GFI can cause
problems.

Why would anyone want to? If the first GFCI is wired so that it protects the
entire downstream circuit, the second one is unnecessary -- and if it's not
wired that way, then the two won't interfere with each other.

This usually happens when a GFCI protected appliance (pressure washer,
boat lift etc) gets plugged into a GFCI protected outlet. It will work
fine.

I believe that GFCI is good for protecting only 6(?) outlets beyond itself.
Can't imagine more outlets that that on one circuit, but that's the NEC (if
memory serves).

Got a citation for that? I can't find anything like that in the Code.
