Yes ,you do need to get full time insurance. This is what the Progessive site says<br><p>The Full Timer's Package provides coverage similar to a homeowners policy and is required for people who use their RV as a primary residence, which is defined as not owning or residing in another dwelling.</p> <p>The Full Timer's Package includes Full Timer's Personal Liability coverage, Full Timer's Medical Payments To Others coverage, Full Timer's Loss Assessment coverage and Storage Shed Contents coverage, as defined below: </p><ul class="bulletList"><li><strong>Full Timer's Personal Liability</strong> — Pays up to specified limits for bodily injury and property damage for which the insured is legally responsible because of an accident. Up to $500,000 CSL coverage is available.</li><li><strong>Full Timer's Medical Payments To Others</strong> — Pays up to $50,000 for medical expenses of others who are injured because of an accident while on the property occupied by the RV that is used as a permanent or primary residence. </li><li><strong>Full Timer's Loss Assessment</strong> — Pays up to $5,000 for certain assessments charged to the full timer while he owns or is a tenant of property in an association. </li><li><strong>Storage Shed Contents</strong> — Pays up to $5,000 for contents located in a shed owned, leased or rented by the insured at the time of loss. </li></ul> I believe that there are only about 4 or 5 companies that offer it.<br>
