Not really.... it's 10x20, but you can roll the sides up fairly easy and give yourself more room. My Z28 fits in with a couple feet of room front & back, and enough room to open the doors about halfway on each side.
$80/month for covered storage with 30 amp service for our 5th wheel (see signature). It stays plugged in 24/7. The storage lot is fenced, gated, the owners live on premises and provide a wash rack and dump station. Rusty
