Advice For Home Protection(needed). Options

Hello,
I was wondering if someone could help me with a problem that's been on my mind lately. Just recently I have taken up residency in a cottage style tent(yes a tent...a modest lifestyle to say the least). Naturally when i go places i tend to worry about whether or not I'll still have a home when i return. Now before you think "this guy lives in a tent, what in the hell could he be worrying about loosing?", the life-style is a chosen one. Little less than a year ago I started studying & practicing Ceremonial Magick. I had just turned 17 at the time and found myself steeped in theory and the gathering of my tools and the assembly of a proper Magickal library, so that i may continue on with The Great Work (in practice as well as theory), when the time came. Needless to say the time has come, and I turn 18 in just a few days. So, a about a week ago a purchased a large tent, and pitched camp in the furthest reaches of my mother's yard of about 2 acres(yes, it's sort of comical i suppose, but i don't yet have the finances for college and am unable to acquire a job until the day of my 18th birthday.). Anyway, now that i have the time, tools, and space to perform the ritual work, I am well on my way. But, like i said when i travel, especially over night trips, i tend to worry whether or not my tools, books and other appliances will be there when I return. Now, I do have the eye-of-Horus hanging at the entrance of the tent and a Eliphas Levi Tetragrammaton pentagram hanging at the rear of the tent. Even though i have much faith in these objects, i do feel the need to know I've done all i can to protect my home and Sacred place of study and practice...Is there anymore I can do? Rituals that can be done?Anything?
Thank you for your time & advice. I hope i haven't rambled too much and the consequence losing your interest and hence your help, I just felt my situation should be stated clearly, so that it may not be misinterpreted nor misunderstood...Thank You.
