Texas · No house policy follows you into the coach
Full-time RV insurance has to carry the liability and the contents, because an HO-3 does not. A mailing address is not Coverage A. This page will not invent a full-timer discount.
A motorhome on a Texas road is a motor vehicle. It needs its own liability at the floor of $30,000 bodily injury per person, $60,000 per accident, and $25,000 property damage, on a policy that lists the coach. The car you tow, or the car that tows a trailer, does not imply the place you sleep. If you sold the house, there is no homeowners contents coverage left behind to stretch. Belongings in the coach belong on the RV form. Collision pays a crash. Comprehensive pays theft, hail, and flood that reaches the vehicle. Those are not a homeowners flood policy, and they are not additional living expense from an HO-3. A total loss is usually actual cash value unless a stated-amount endorsement says otherwise.
The wider picture: Texas RV insurance. Why you do not park the policy for the winter if you live in it: year-round. If it has no engine: travel trailers. A parked car is a different problem: a car that is not being driven. The auto floor that does not list the coach: car insurance in Texas. The state hub: Texas insurance.
