This is something I can do.
I realize advertising here without payment circumvents the Wacco process, so please consider my response only an attempt to help your friend.
I will briefly mention that I've been trained by Build it Green as an advanced Certified Green Builder, by the Building Performance Institute as a building Analyst and building shell/envelope specialist, and I have participated in weekend workshops about trailer homes specifically with Jay Shaffer and Tumbleweed Homes.
You may pass along my contact # 861-0669 or email address to your friend.

I have a friend who has an old motor home type trailer that she would like to have rehabbed to be a livable unit. Is there anyone out there who can do this kind of work?
