We are having difficulties figuring out the shorepower. Everything
was working fine on 30A, but now that we have moved to a new dock
where there is only 110 we have attached our pig tail to take the 30
to 110 but it trips the breaker on the dock as soon as we plug it in.
We tried using the neighbour's pigtail (which works for him) and it
still trips it. We have the Xantrex inverter/charger and have
adjusted the powershare level to 10 (from 30).

Any ideas?

after shutting off all breakers in the 120 v circuit, put a voltmeter
inline with the pigtail to see if, in fact, you are still drawing
current. I'll be you are. You will need to trace / fix that.

You probably have an unswitched appliance

Volt meter? Inline? To measure current? Huh?

Yeah, stupid me. I mean multimeter.

Hmmm. You have a multi-meter that'll directly measure more than a few
milliwatts?

Mine is a digital with a ten amp fuse on the Amp function. Fluke 87 as
a matter of fact. All the professional heating and cooling guys, and
the appliance repairman, seem to have one like it.

That's well and good, but an ammeter with a 10A fuse may not be very helpful
in a circuit that's tripping a 15A breaker. I think I'd start by removing
all the power and using the 87's ohm meter function.

A good digital you can plug it into a wall socket with it on Ohms
without damage.

Ho-hum....A 10 Amp range is not unusual in a digital MM
But a power scale is rather unusual - except the dB scale that makes
some load presumptions - that you may be referring to?
