This guide is general. It does not read any particular contract or any state's rules, and it does not describe which items a named company's contract covers.
Most people compare terms first and then count what they need covered. Reverse that order. Count the household's items first, then match the term to the list.
Make the inventory
List every vehicle and every home system that a contract might cover. For each item, write the type, the make and model, the identifier the contract will use, the age at the date of sale, the way it is used, and where it is kept. If an item is shared, write down who else uses it or lives with it.
Check the age and use
Ask whether the contract covers items of every age that you own. Some contracts limit coverage by age, by mileage or hours of use, or by type of use such as commercial or rental. An item outside those limits will not be covered whatever the term. Mark each item as inside or outside the limits in each offer.
Seasonal or occasional use can matter. A unit that sits idle for part of the year may be treated differently from one in daily use, so write down the actual pattern rather than the expected one.
Check the location
Write the place each item is kept and the state where it is registered or located. The rules that apply to a contract may depend on that state. The state pages on this site name the regulator, the statute, and the roster date for each state, so use them to check the location before you sign. A move across a state line can change the rules, so ask what the contract does if the location changes.
Check the add and drop rules
Ask whether a unit can be added to the contract after the start, and on what terms. Ask whether a unit can be taken off, whether any refund applies, and what notice the change requires. A household whose items change over time needs a contract that can change with it, and the paper should show how that works.
Match the term to the list
Only after the inventory is complete, compare the terms against it. Put each item on its own row and mark whether each offer covers it under the age, use, location, and add or drop rules. An offer that covers the main vehicle but leaves out the second one is a different size from an offer that covers both. Read the coverage line for each item rather than the total.
