We had a Class c for many years when the kids were around. Had a 2 family family so 4 kids and keep them comfortable and busy while travelling was important at the time. Our unit worked out real well for many reasons mostly in the travelling part by keeping them busy with TV, movies etc. while travelling down the road.
The down side was the setting down all the time as we didn't have a toad in tow figuring with all the bodies we would need another bus. Since then the kids are all gone now and wife and I have switched to a TT.
For the 2 of us it is great but if we had the 4 kids and the trips we have done I would not have wanted to do it with all 4 riding in the cab of the truck.
Buy whatever works for you and take pieces of advice for all that have been there and done that.
