Should I call the cops?

We live full time in an rv because of my husbands job so we’ve been renting a lot in an rv park for about 1 year and a half. Most of the time we’ve been here we’ve had the same neighbor. He’s maybe in his mid/late 60s a little on the bigger side and he lives alone, his license plates aren’t from this state and from what we know of him is that he travels to different states for a few months. We’ve spoken to him here and there and he’ll say hi when we see eachother outside. He has a routine, I guess? Most of the day he’ll open his door and leave it that way most of the day, he goes and gets groceries at least once a week or once every two weeks. I know all this because I always have windows open so my kids can look out the rv and to have light coming in. With covid I don’t do much so I’m here 24/7 even if my husband is home. The last few days there hasn’t been much movement on our neighbors side. The doors haven’t been open, truck hasn’t been moved he used his kayak and fishing rods early last week and they’re still loaded on his truck, he usually closes his blinds at the end of the day everyday and reopens in the morning and they’ve been open for almost a week. We’re all sick and waiting for our Covid test results so we don’t want to go knock on his door have him open and risk getting him sick, I’m getting really worried that somethings wrong but I don’t want to call the rv park or police and nothing is wrong and he’s just changed his routine or something. I’m a very nervous person and never dealt with something like this so I’m not sure what to do
