When I lived in Florida I bought my Champ in Milwaukee. I did all my homework before I left. Seller was very cooperative. I had insurance arranged before I left Florida. Got there, looked the boat over, went for a test run and then to his bank where I paid off his note and gave him the balance in cash. Everything worked flawlessly. I went to the hotel with the boat. Next day I had already scheduled with a service center to have my tranny serviced and the wheel bearings on the trailer serviced. By noon that day I was on the road to Aurora Canvas to get a custom cover. After that back to Florida. No problems .
Make sure you cover all your bases before you leave home.
