I would make my sleep system cheap. A blue ccf pad (optional), a polycro tarp and the cheapest fleece blanket or bed quilt depending on the forecast. I mean it's only one night, I've spent that sitting out before while trapping in Indiana, where I grew up (similar geo) with just a hunting coat and layers underneath. I'd spend the rest on my cook kit and a big steak, potato, six pack and some ridiculously good desert to make them envious. Throw everything in your blanket or quilt to make a bag to sling over your shoulder.
