If you get it above the roof of your trailer, the heighth isn't going 
to make that much difference.  You need a good bround.  I have a friend 
who has one mounted on the gack of an ex tera on a trailor hitch and he 
just took third place in an antenna contest at a ham fest last week end 
and he always puts out one of the best mobile signals I've heard.  I'm 
considering getting a scorpion to put on top of this metal house I live 
in as a second and spare antenna. ]
