Looking into installing a AC unit into my 7x12 enclosed for obvious reasons. I figure we got atleast a few trailer camping vets I could petition. I think I speak for everyone that attended VIR's last July event, those 100+ temps nearly knocked my ass out :box: The trailer I have currently has a roof vent, so I'm gambling the idea of a used RV roof ac unit. These suckers are going for over 400 new. Hellz nawww. Seeing a few good deals on craigs, though. Have any of you guys installed a window unit into your trailer? Not a big fan of cutting a huge hole in the front of my very expensive 7x12, but with some of these temps we've been getting, I'll do it as a last resort.
