Full size tractor unit empty fuel efficiency. Best one?

having watched a few vanlife youtubers vids it seems the bigger the vehicle is the sooner they want rid of it . The cost of fuelling it is the killer and the big needs big tyres etc all sour the dream badly by all accounts

You’re right about the fuel. Two days ago we were heading into a gale and boy, was I grumpy. Yesterday it had swung round so I cheered up a bit. Today it’s the mountains. The only good thing about the trip is that we will be parked up and working for 19 weeks when we get there. The other half thinks we should tow a little runabout behind the truck but I’m not so sure.
