I own a Vegas. The differences in the Axis and the Vegas are mostly cosmetic. Find the floor plan that meets your needs and go with it. 60 mph = 11.4 mpg. 70 mph = 9 mpg, with a toad 8 1/2 to 9mpg at 60mph. I had some small issues and Richards Motor Sales was there for me. I had to drive to Reading MI to pick mine up but I saved almost 5K on my next best price. I upgraded my A/C to the 15000 and its well worth it. As long as you have over 1/4 tank of gas you have a generator. I tow a toad with mine with no problem. Talk to Chris, he's an aggressive seller and will answer all of your questions very professionally, he knows his units. I have become pretty good friends with him after the sale. His cell is 1-517-398-5070 tell him Hoppert Builders told you to call.
