Don't try to plug into a 220v dryer or welder outlet. they look the same but you will fry your electrical appliances in your trailer.
I don't think so.
Why do YOU think that ??
To summarize:
If the houses don't have an appropriate 220 receptacle OR a 30 amp 110 one (highly unlikely) then you MUST run your generator.
If you don't have a generator......then you will be hot.
What you are doing now is dangerous; it's a fire just waiting to happen.....maybe inside the house where it's plugged in. I kind of wonder why the breaker in the house box doesn't trip. Mine did when I tried it.
