We considered a small Class C for a daily driver. Yes the gas would be more expensive but so is having another car with gas, insurance, maintenance etc.
We then transitioned into thinking about a hefty truck with a drop in camper. That way, when not on the road, the camper could be left behind. And, when traveling, the camper could be dropped freeing the truck to travel into areas a C or the truck with a drop in couldn't go. Logistically the drop in camper seems to work best but of course it is smaller, doesn't have direct access between the driver seat and back etc. Tough choice.
Then we got lucky and got a great deal on a 4x4 Provan pictured in the signature. It has the best of both worlds but you have to get lucky on a used one since they are ridiculously expensive new.
We will probably still add a small, high mileage car for fear of future sky high gas prices even though the Provan has the footprint of an F-350 and would probably work as a daily driver. I don't know what we would have done if the Provan didn't come along.
PS: One last item to consider. Using a very expensive camper as a daily driver shortens it's life. So, is it better to have a small car to minimize mileage on the expensive camper or is the savings of not having a car worth the extra wear. Again, a drop in camper solves that. Just leave the camper at home when not traveling. But yes, the drop in vs a traditional C issues come into play.
Like everything else. For every plus one choice has, it has a negative that the others don't. Good luck in your decision.
