Our 96 Southwind has 4 speeds. (ovedrive). I don't know when the chassis manufacturers went from 3 speed to 4 speed.
Personally, I don't think it would be worth the price to change the transmission, unless the RV has a bad transmission.
You're definitely not going to get good MPH cruising at 70. I think you will find most agree around 58-62 MPH is the most economical speed for motor homes.
I'm guessing an older 3 speed Class A traveling at 70 MPH will get about 5 MPG, or less.
If you're looking for better MPG, spend the money and get a Class B.
Keep us updated on what you decide.
