Yes, and a heated+refrigerated truck for most of the north. It would be unacceptable to have the engine running the whole time. I think it's doable in theory with a truck that has giant electric batteries, e.g. a Tesla Powerwall or two. Maybe a specialized RV cwould have it.

Or a diesel generator. But that's an ongoing vs capital cost question I guess.

Diesel exhaust is never good for you. It also risks being noisy. The noise attracts unwanted attention too.

Imagine an RV with sufficient batteries that can be charged at an electric fast charging station. That's all you need, but I don't think it exists.

There are propane-powered appliances intended for RV use.
