I see your subj is EU2000i 2KW Honda Generator. This is very popular amoung the RV'ers her due to its small footprint and weight.
Being small wattage of course you not be able to power up your whole trailer but it will produce 1600 watts or so to run alot of thing. Mine will not run my 13,500 Air conditioner however.
We camp alot alot off the power grid and the 2KW Generator is perfect for this. We have beefed up our trailer battery system to run all of the 120VAC items we want to have running and all the 12VDC items we want direct connected to the battery bank. The battery bank has been planned out to run all of these things usually starting at 6PM to 11PM each day and will still have a good 50% charge state left over at 8AM the next morning.
This is when we connect our 30AMP Trailer shore power connection to the 2KW Generator using a RV30Ap15A long adapter and then using our on-board smart mode converter can recharge our batteries back up to their 90% charge state in a quick three hour generator run time. Most of the place we go to all have generator run time restrictions in place so this works out perfect for us. With the 90% charge state we do all of this all over again the next day/night run off the battery bank.
You will find a bunch of info like with just about anymore you run across on the forum here.
ALot of forum members only give you short quick answers and others like me like to pass on alot of things that may or not be of most importance to the asked question hehe...
