Insurance

[pat]

After 5 short years , Ill be driving my truck within a week or so. I need insurance. My daily driver has always been on my dads insurance plan with State Farm.
Im 22, with no wrecks or anything on my record. I wont be using my truck every day, but I want to use it way more than just going to shows. I would like to get theft coverage, basically full coverage for my truck. A couple problems maybe though, I dont have a lockable garage to keep it in, my daily driver is on my dads plan, and Im going to use it more than just shows. I figured I would insure it for about 20k if possible.

Any pointers?
Thanks
