can I mount this in an enclosed trailer and wire some outlets to it and plug power into it will it work that way

If you are going to attempt this I would run it into a circuit breaker box with a 30 Amp main breaker, and then feed your individual circuits from that box. But note that you will then need a transfer switch if you want to also be able to power it from commercial power when that is available. In any case there needs to be at the very least a circuit breaker rated at 30 Amps or the rating of your outlets, whichever is lower (probably 15 Amps) between the generator and your outlets. You might want to talk to an electrician about this but the bottom line is you need some form of protection, otherwise the trailer could catch fire as a result of overloaded wiring.

I wouldn't recommend it. You need to have a safety valve so to speak some where in between the outlets and the power source. If you are using 15 amp outlets and trying to push 30 plus amps through them it might cause an issue. I'm no electrician but it seems a little dangerous if what I am reading you want to do is what I think it is.
