If I had the budget for it, I'd definitely consider a toad, just because driving around in a small car is a lot better in the MPG department than using the mother ship. A used Jeep Wrangler is always a tempting choice.
If possible, I prefer electric brakes and a towing brake controller.
Another advantage is that you have two vehicles, and can hold down a site with something a lot more substantial than a sign when out for groceries. A sign can "blow away in the wind". Someone moves a toad... there are felony charges that will have to be answered.
