We travel full time in the 32ft. we have made several posts to our blog about our actual mpg.
gone with the wynns the 35ft should get very close to the same as ours. We get anywhere from 11-14 just depending on if we are in the mountains or not. that is with a tow car. I do my own math, the onboard computer is always a little off, so i don't trust it to give me the true mpg. If you are considering purchasing a vesta, i am more than happy to answer any other questions you have or tell you my personal likes and dislikes.
