Some do, some don't allow suspension. You got the items right. You would never suspend comprehensive sue to limbs falling, etc. Depending on what you suspend, you might not have coverage if someone Else hit you at a storage lot.
Also be VERY careful about suspending liability coverage if there's any chance you will be taking the unit out to run the engine or alternator, take it for repairs, fill up the propane, etc. Murphy's Law: the one time you have an incident is the one time you forget to reinstate coverage. Also, you don't want to have one of those "Oh honey, I thought you called the insurance company" "No honey, remember, you said you were going to call the insurance company as soon as you got home from work" kind of discussions!
