I have a slide in camper for my 4x4 long bed Cummins. The truck is on 35” ridge grapplers and got about 17.5 mpg on the freeway doing 75mph. It can get 19-20mpg with nothing in the bed. With 60 gallons of fuel I have over 1000miles of range. I also have a 3900lb dry (closer to 4500lbs with food and supplies) 22’ Winnebago micro Minnie 2108FBS that I get 15mpg towing the same speed.
If I dropped to 60mph and stayed in the slow lane, it’d probably get about 10% better mpg. If I had factory size H/T tires even more. Guys with factory size tires report 23mpg empty.
No way a CT will replace that anytime soon.
Here’s a picture coming home from where I bought the slide in camper in Utah. Currently building out the camper, installing solar, cutting in windows, etc with an expected final weight of approximately 1500lbs. MPG will likely fall to 16.

Also has a BW gooseneck hitch for hauling equipment. It is like a Swiss Army knife. There is nothing a CT can do better than a 20 year old diesel except 0-60.
I think folks were expecting more. That’s the issue here. Alas, the CT is just a big MX with a bed, like a modern day BEV El Camino.
