Extensive traveling to me says moho and toad for sure.
Nowhere near planning, but just thinking....kids are 13 and 16, got a few more years to go yet, but I'm solidly in the super C/ small class A pusher camp currently. More likely an A because bang for the buck seems higher with used diesel A's than diesel super C's just more to choose from = lower price for comparable miles and size.
Priorities would be fuel mileage, because travel means travel to me, not 200mi every 5th day on average, but rolling don the road burning some serious dead dinosaurs.
Towing something, toad or a toy trailer would be a must for me, so towing capability and economy doing it would be a priority.
Just where my head's at on this.
