The way you use your truck will determine how you insure it. If you use it as a daily driver it will be hard to get classic insurance on it. I use Hagerty myself and there is no limit on the miles I drive them. But I had to show proof of insurance for daily drivers for both me and my spouse, even though we're retired and don't drive daily.
There's a good tech tip on insurance on this site.
