We use our 2KW Honda Generator all the time that is cable secured in the tail gate corner of my Truck Bed.
We just plug the Trailer shore power cable into the Generator 120VAC receptacle using a RV30A-15A long Adapter(WALMART) and just run the trailer on-board converter/charger unit to re-charge our battery banks each morning when allowed to run my generator. Since the trailer is using a SMART MODE PD9260C COnverter it recharges my 255AH battery bank from a 50% charge state to a 90% charge state in as little as three hours of generator run time. Once my batteries are back up to their 90% charge state then I can use the Trailer again for the next day/night run off the batteries.
Some folks will have a GFCI problem which needs the generator receptacle to use a BONDING plug but that is not the case for us. I do however have an optional 1500WATT PSW INVERTER that runs off my my battery bank and produces 120VAC power. When I plug the trailer shore power cable into this connection I sometimes get a GFCI fault on the trailer side. If this happens then I have to plug in a BONDING plug into the unused INVERTER 120VAC receptacle plug.
My generator is not physically frame grounded to anything. My 1500WATT optional installed INVERTER does have a trailer frame ground cable installed.
If you are not having GFCI issues in your trailer then I would not worry about grounding anything... The WHITE NEUTRAL wire coming from the generator 120VAC RECEPTACLE is NOT connected to your generator FRAME GROUND. The GREEN GROUND WIRE from the generator 120VAC RECEPTACLE 'IS' connected to the frame ground terminal on the generator frame. By running a ground cable from the generator to an Earth Ground Rod is only grounding the generator frame and the GREEN wire going to the generator load plugged into the 120VAC receptacle.. To provide grounding that is like what you get from SHORE POWER CONNECTIONS you will need to use a BONDING plug on the generator 120VAC receptacle- Do a search on GOOGLE to read about this...
My BONDING PLUG looks like this... You can see a wire is connected between the GREEN and WHITE WIRE connections on the BONDING PLUG.
This is only relative for my setup here and may be different for yours... I have confirmed my Generator Grounds using a multimeter here in my setup.
