Our insurance is similar to what Rob stated. As for examples, when we chose our coverage, we were able to choose coverage to either pay us a depreciated value if the trailer is a total loss or to pay us the value of a comparable replacement "new RV". Every year our insurance goes up because we consistently choose the "replacement value"... When we started, the replacement value was around $35K. Today, the replacement value is a tad over $75K. So, we pay "more money for more insurance" if we have a total loss. Additionally, we have replacement value for the contents. That way, if things are stolen or damaged in an accident, the insurance pays to replace the items, not just reimburse us "pennies on the dollar in depreciated value"...
So, pay attention to what your policy says, and if you're on a trip, you may have "lodging coverage" on your vehicle if your trip is interrupted by an accident involving something being towed by that vehicle.... While many parts of your policy may not include both, parts of it MIGHT include both, so read carefully and/or ask your "trusted insurance agent"... ( not necessarily the phone tree in the nationwide claims reporting center).....
ADDED: Also, don't get confused between an "automobile policy" which limits the amount of content value to a specific dollar figure (usually around $1000). Most "RV specific insurance" is similar to "home insurance" and you can choose the amount of content insurance as well as choose "depreciated value for a loss" or "replacement value for a loss"... Going into an insurance office and saying, "I want to insure my travel trailer" might get you adequate coverage or it might get you "money thrown away if you have a total loss"... CHOOSE WISELY !!!!!
