I think that you should seriously reconsider towing another vehicle with you at all times. On a typical trip of 7000 miles, it is not unusual for us to put 3000+ miles on the toad. Besides that, with your family, there is a safety factor. If your coach breaks down, with a toad you have transportation available for them to go to the nearest place of comfort. Without a toad, you are at the mercy of whatever happens by at the area where you are stranded. After many years of RV travel, we will never make a trip without our back-up vehicle, just in case something breaks. If you read the forums a lot, you will find that things do break and sometimes they break at the most inconvenient times.
