Hi ktmrfs,
When I wrote PD they told me all their units are a power factor of 0.7. So the 1300 watts becomes about 1857 va. Not pretty with a genny rated for 1600 va. Then take it up above sea level. If the battery bank is truly flat with six six volts it is not going to be reliable.
The only reason it would work is if the pd doesn't zip up to full output i.e. with sagging voltage. I have seen that in person with the 40 amp pd in the RV I call home probably because the maker skimped on the wire size from the converter to the battery bank.
The person might consider solar?

True, the PD80 may draw about 1300 watts, but closer to 1600-1700 VA, so it's marginal on a honda 2000, right at it's continous rating. Like so many RV appliances, actual current draw is more than the "watts" rating indicates.
The PD60A draws on the order of 1400VA IIRC my measurements on one supplying 55A.
