Kenny, I see it's been a few days with no replies. I suggest you just search this forum for "Grand Tour" and you will find many folks posting about issues and features of the GT. Maybe not on the 45 model, but certainly a lot on the 42 ft models.
That's a lot of money and I'm sure you want to spend it wisely.
