Regarding the "possibly" missing motorcycle gear, first look around and make sure that's where they were. Second, check your calendar and see when the next time is that you are going to need them. Third, send him a text up to one week before the date you need them to tell him you can't find them and does he know where they are.
Yes, I know you don't own a motorcycle. My point is, you have no reason to be looking for that stuff. He may very well be testing you to see if you are checking up on his activities. You didn't rise to the bait on the camping stuff, so now he's trying this. Don't give him the satisfaction.
As for the opinion of the divorce support group, I would tend to concur. He is just doing a more thorough job of preserving his options than most wayward spouses are capable of.
