2020 Thor four winds 28a RV
I just acquired an 28ft new rv. It's really bad on gas 8mpg and I was thinking of ways to improve its mpg. I was thinking to add 2 10hp electric motor with a pulley connecting to the drive train. And connecting that to 30 200ah lithium 12v batteries. Other than doing that I can look into inwheel for my rear tires. I'm new to electric car so I don't have much experience so if anyone can give me pointers.
