Towing mileage/capability
First, I did see a 'what are you towing with?' post. Be darned if I can find it. I'm happy to read suggested posts if you point me to them. We have a 2021 Wolfpup 16fq, 3200 lbs, nearly 12' hig...

For the record. No, I'm not looking for something for nothing. Physics still apply. However, fuel efficiency has improved quite a bit over the years and you'd think there might be more fuel efficient options to tow 4000lbs than a full sized V8 getting 8-10 mpg.
The problem is most of those improvements have occurred when the demand on the engine is light.
- variable displacement (they turn off cylinders under light load)
- Stop-start (they turn off the engine when stopped)
- Hybrids (they fill the battery when under light load and use that stored power under heavy start up loads)
- Etc...
Problem is none of that really applies to towing. Your typical RV'er gets on the freeway, gets up to speed and holds it there. There is negligible light load operations to save much fuel. Under heavy load, 10-20yr old motors were already operating pretty darn efficiently.
And, given the percentage of time people tow and the rules for how the govt punishes poor fuel economy, the manufacturers don't really have a lot of incentive to improve towing efficiency even if there was much room to do so.
