The main issue is to not overload a unit. If a Honda says 2000 check
the real ratings, it may be 2000 rated with No surge capacity, meaning
it may only run and start a 300 watt motor, or the motor won`t start or
you will kill the gen. Honda uses run watts as ratings, and for
longevity those are peak loads I would never maintain continuosly.
Others like Generac rate load and surge, a 4000EXL Generac is rated
4000, with 6000? surge? , a fine unit with oil filter, electric start,
and regulated power, althought not as clean as the EU inverter series,
but it is Noisy!!. www.northerntools.com has honda motor units with
cheaper heads avalaible and offers Dual or Tri Power fuels. NG , or
running off your bulk propane is great, no gas stations to find, and
during power outages the gas station is often shut down also, no power
to run out, and the motors last longer, the oil does not contaminate.

Bottom line you need excess capacity and surge capacity. Always
oversize a bit, do your own audit, with a digital clamp on amp meter
with peak hold function, and a Kill-A-Watt meter, undersize and your new
gen will not start apliances, or blow out early.
