We are brand new to RVing. Just bought our first RV and haven't evne been anywhere yet. We have 6 kids, of which 4 will likely travel with us. My mother and my mother-in-law are also likely to travel as well. Needless to say, we need space in our tow vehicle. I have a Jeep Grand Cherokee 4x4 which I know I can tow 4 wheels down but it only seats 5. We may be able to squeeze 6. I also have a full size conversion van that I would like to tow. I am also aware that I will not always have all of the kids with me. For instance this weekend we are planning a trip to Savannah, Georgia with just four kids and my mother. In this case, the Jeep could work. In researching this it appears I have two choices: I can get a tow bar and a driveshaft disconnect and tow it with 4 wheels down. The cost for this seems to be approximately $2,500. $1,00 for the tow bar and $1,500 for the driveshaft. I could also get a heavy duty dolly like the Demco Kar Kaddy. I assume the vehicle would have to be towed backwards. The dolly sells for around $2,500. It seems to me that the dolly is better because I can use it to tow any vehicle, whereas the towbar will only work for the vehicle that has the driveshaft disconnect. Is there a disadvantage to towing with a dolly? Is a conversion van too heavy to tow? What about renting a car when you get where you are going? I know this is a long post and I apologize, but I am so new to this I don't know where to begin.
