I always tow my Corolla on a dolly everywhere we go even locally. I would be lost without a way to go places where I am staying. As far as fueling I look ahead at where I can get fuel and have never had a problem getting it. Sometimes I may need to get it sooner than I need too, but we do have a long range for fuel. I also have a V-10 in my 27 foot and I have always been able to pull the car and dolly up the mountain passes even in Colorado. I might be going slower, but by going slower I am getting to see more also. JMT
