If you leave the 120 V circuits alone and add a few 220 volt outlets at strategic locations for your portable appliances, feeding them with a tee off the shore power connection, you could then use some local devices in the trailer that weren't dual voltage. Also, if you are going to be using a generator all the time anyway, you could use a 120 volt generator and just put a small stepup transformer in for the few 220 volt plug outlets you want. When you add up all the changes to the trailer it may get costly. Having a dual voltage trailer (and you just decide which devices to run on each voltage) would be simpler than the paradigm that says you take a 120 volt trailer and change everything to run on 220 v because that is what Chile uses. Especially when you are unlikely to find shore power connections everywhere you want to camp.

Thanks Jeff, I think you are absolutely right. So far the big 220>110v big transformer and a +3kw portable generator seems the best idea. This way i donīt need to replace the AC. Already contacted Domenic and they donīt build 220v or universal units.

Rewiring a separate circuit just for the wall sockets so they can be plug to a external 220v source sounds great :

- Circuit 1 : external 220v power > 220v to 110v transf. > everything except wall plugs remains 120v factory standard.

- Circuit 2 : external 220v power > directly to the wall sockets circuit (cut and separated from the 120v circuit 1) > 220v wall outlets inside trailer.

The question for circuit 2 is where these internal wall sockets wiring come together...

Please let me know what you guys think.

Regards

BTW, just found out that you can connect two Honda EU 30 generator in order to get the performance of a 6kw generator. You may ask why not get a 6Kw generator in the first place (which is a little bit cheaper) ?. Well if itīs cold you might not need the AC and 6Kw will be too much. Also the 6Kw weights about 120kg (260 lbs) so it would be almost impossible for one person to move it in case you want it apart from the trailer (noise). The 3Kw is about half weight.

Do you need 6000W? 3000W should be about right even with the AC.

Not really sure. Surely I can start with 3kw and if itīs not enough then get a second one and tie them in parallel.
