The way I see this whole MPG thing is that I get 23 MPG pretty consistently. The way I figure is that I put as many miles on my tow car as I do on my MH. I will set up camp and explore in the tow car in a radius around the camp site then move on. I have keep accurate records of Mpg over 75k miles of travel. So my MH gets 8.7 Mpg and my tow car gets 40 mpg so if equal miles is put on each I come up with 23 mpg ave. I would suspect that many on this forum put double on their tow car because they stay longer at a camp site which would raise the Mpg even higher if you tow a small high MPG tow car. Wouldn't the total fuel usage be a better way to look at it?
