Given the "rig" you have, I would not recommend just leaving it unprotected on your undeveloped property. With regard to storage, I would also check the Cookville area. It's a larger town, is only 25 miles West of Crossville, and there is a straight shot(TN-62)across to the area where you are building. You might find something less expensive between Lebanon, Cookville and Crossville. When you get here, be sure to check out the Tennessee Good Sam web site "tngoodsam.com" and find a local Good Sam Chapter to camp with. They will help you familiarize yourself with the area and better enjoy your camping experiences, as there is a lot to do and see here in Tennessee.
