Preferences on pulling a toad, or rent when there?

Our choice is to pull a toad all of the time. We don't even feel it back there and have it when we want it. When we go across isolated areas we have a sense of security with it back there. If we break down we are not stranded. We get the same MPG with or without it which was also the case in our last coach which was a 37 foot gas coach. "We would not leave home without it"
